Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538784, here are decompositions:

  • 7 + 538777 = 538784
  • 13 + 538771 = 538784
  • 61 + 538723 = 538784
  • 73 + 538711 = 538784
  • 163 + 538621 = 538784
  • 223 + 538561 = 538784
  • 271 + 538513 = 538784
  • 313 + 538471 = 538784

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 538,784 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 538784 first appears in π at position 36,146 of the decimal expansion (the 36,146ordinal-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.
