Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538672, here are decompositions:

  • 23 + 538649 = 538672
  • 83 + 538589 = 538672
  • 149 + 538523 = 538672
  • 191 + 538481 = 538672
  • 389 + 538283 = 538672
  • 509 + 538163 = 538672
  • 521 + 538151 = 538672
  • 593 + 538079 = 538672

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 538,672 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 538672 first appears in π at position 240,438 of the decimal expansion (the 240,438ordinal-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.
