Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175420, here are decompositions:

  • 17 + 175403 = 175420
  • 29 + 175391 = 175420
  • 59 + 175361 = 175420
  • 71 + 175349 = 175420
  • 191 + 175229 = 175420
  • 317 + 175103 = 175420
  • 353 + 175067 = 175420
  • 359 + 175061 = 175420

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 175,420 and was likely granted around 1874.

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

Position in π

The digit sequence 175420 first appears in π at position 909,240 of the decimal expansion (the 909,240ordinal-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.
