Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001864, here are decompositions:

  • 43 + 1001821 = 1001864
  • 67 + 1001797 = 1001864
  • 151 + 1001713 = 1001864
  • 181 + 1001683 = 1001864
  • 271 + 1001593 = 1001864
  • 277 + 1001587 = 1001864
  • 313 + 1001551 = 1001864
  • 337 + 1001527 = 1001864

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,001,864 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1001864 first appears in π at position 469,986 of the decimal expansion (the 469,986ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
