Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526810, here are decompositions:

  • 29 + 526781 = 526810
  • 47 + 526763 = 526810
  • 71 + 526739 = 526810
  • 101 + 526709 = 526810
  • 107 + 526703 = 526810
  • 131 + 526679 = 526810
  • 173 + 526637 = 526810
  • 191 + 526619 = 526810

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 526,810 and was likely granted around 1894.

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

Position in π

The digit sequence 526810 first appears in π at position 426,187 of the decimal expansion (the 426,187ordinal-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.
