Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172282, here are decompositions:

  • 3 + 172279 = 172282
  • 23 + 172259 = 172282
  • 59 + 172223 = 172282
  • 83 + 172199 = 172282
  • 101 + 172181 = 172282
  • 113 + 172169 = 172282
  • 233 + 172049 = 172282
  • 251 + 172031 = 172282

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 172,282 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 172282 first appears in π at position 918,289 of the decimal expansion (the 918,289ordinal-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.
