Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972138, here are decompositions:

  • 5 + 972133 = 972138
  • 7 + 972131 = 972138
  • 17 + 972121 = 972138
  • 19 + 972119 = 972138
  • 47 + 972091 = 972138
  • 59 + 972079 = 972138
  • 67 + 972071 = 972138
  • 107 + 972031 = 972138

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 972,138 and was likely granted around 1910.

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

Position in π

The digit sequence 972138 first appears in π at position 135,578 of the decimal expansion (the 135,578ordinal-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.
