Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472138, here are decompositions:

  • 5 + 472133 = 472138
  • 11 + 472127 = 472138
  • 71 + 472067 = 472138
  • 179 + 471959 = 472138
  • 347 + 471791 = 472138
  • 389 + 471749 = 472138
  • 419 + 471719 = 472138
  • 461 + 471677 = 472138

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 472,138 and was likely granted around 1891.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 472138 first appears in π at position 962,594 of the decimal expansion (the 962,594ordinal-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.
