Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145330, here are decompositions:

  • 23 + 145307 = 145330
  • 41 + 145289 = 145330
  • 47 + 145283 = 145330
  • 71 + 145259 = 145330
  • 137 + 145193 = 145330
  • 191 + 145139 = 145330
  • 197 + 145133 = 145330
  • 239 + 145091 = 145330

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 145,330 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 145330 first appears in π at position 215,464 of the decimal expansion (the 215,464ordinal-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.
