Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511882, here are decompositions:

  • 23 + 511859 = 511882
  • 71 + 511811 = 511882
  • 89 + 511793 = 511882
  • 179 + 511703 = 511882
  • 191 + 511691 = 511882
  • 251 + 511631 = 511882
  • 359 + 511523 = 511882
  • 419 + 511463 = 511882

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 511,882 and was likely granted around 1893.

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

Position in π

The digit sequence 511882 first appears in π at position 871,469 of the decimal expansion (the 871,469ordinal-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.
