Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145926, here are decompositions:

  • 23 + 145903 = 145926
  • 29 + 145897 = 145926
  • 47 + 145879 = 145926
  • 97 + 145829 = 145926
  • 103 + 145823 = 145926
  • 107 + 145819 = 145926
  • 127 + 145799 = 145926
  • 149 + 145777 = 145926

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 145,926 and was likely granted around 1873.

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

Position in π

The digit sequence 145926 first appears in π at position 758,545 of the decimal expansion (the 758,545ordinal-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.
