Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538212, here are decompositions:

  • 11 + 538201 = 538212
  • 13 + 538199 = 538212
  • 53 + 538159 = 538212
  • 61 + 538151 = 538212
  • 89 + 538123 = 538212
  • 139 + 538073 = 538212
  • 163 + 538049 = 538212
  • 193 + 538019 = 538212

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 538,212 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 538212 first appears in π at position 260,374 of the decimal expansion (the 260,374ordinal-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.
