Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538888, here are decompositions:

  • 11 + 538877 = 538888
  • 17 + 538871 = 538888
  • 47 + 538841 = 538888
  • 59 + 538829 = 538888
  • 71 + 538817 = 538888
  • 89 + 538799 = 538888
  • 137 + 538751 = 538888
  • 149 + 538739 = 538888

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 538,888 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 538888 first appears in π at position 179,165 of the decimal expansion (the 179,165ordinal-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.
