Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487882, here are decompositions:

  • 53 + 487829 = 487882
  • 71 + 487811 = 487882
  • 89 + 487793 = 487882
  • 113 + 487769 = 487882
  • 149 + 487733 = 487882
  • 173 + 487709 = 487882
  • 179 + 487703 = 487882
  • 191 + 487691 = 487882

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 487,882 and was likely granted around 1892.

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

Position in π

The digit sequence 487882 first appears in π at position 7,950 of the decimal expansion (the 7,950ordinal-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.
