Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006438, here are decompositions:

  • 5 + 1006433 = 1006438
  • 47 + 1006391 = 1006438
  • 71 + 1006367 = 1006438
  • 101 + 1006337 = 1006438
  • 107 + 1006331 = 1006438
  • 131 + 1006307 = 1006438
  • 137 + 1006301 = 1006438
  • 197 + 1006241 = 1006438

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 1,006,438 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 1006438 first appears in π at position 110,648 of the decimal expansion (the 110,648ordinal-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.
