Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145594, here are decompositions:

  • 5 + 145589 = 145594
  • 17 + 145577 = 145594
  • 47 + 145547 = 145594
  • 83 + 145511 = 145594
  • 107 + 145487 = 145594
  • 131 + 145463 = 145594
  • 233 + 145361 = 145594
  • 311 + 145283 = 145594

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 145,594 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 145594 first appears in π at position 900,749 of the decimal expansion (the 900,749ordinal-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.
