Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145510, here are decompositions:

  • 23 + 145487 = 145510
  • 47 + 145463 = 145510
  • 59 + 145451 = 145510
  • 149 + 145361 = 145510
  • 227 + 145283 = 145510
  • 251 + 145259 = 145510
  • 257 + 145253 = 145510
  • 317 + 145193 = 145510

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 145,510 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 145510 first appears in π at position 970,086 of the decimal expansion (the 970,086ordinal-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.
