Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538172, here are decompositions:

  • 13 + 538159 = 538172
  • 79 + 538093 = 538172
  • 181 + 537991 = 538172
  • 331 + 537841 = 538172
  • 379 + 537793 = 538172
  • 433 + 537739 = 538172
  • 463 + 537709 = 538172
  • 499 + 537673 = 538172

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 538,172 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 538172 first appears in π at position 484,077 of the decimal expansion (the 484,077ordinal-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.
