Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538810, here are decompositions:

  • 11 + 538799 = 538810
  • 47 + 538763 = 538810
  • 59 + 538751 = 538810
  • 71 + 538739 = 538810
  • 89 + 538721 = 538810
  • 101 + 538709 = 538810
  • 113 + 538697 = 538810
  • 257 + 538553 = 538810

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 538,810 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 538810 first appears in π at position 105,688 of the decimal expansion (the 105,688ordinal-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.
