Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174242, here are decompositions:

  • 73 + 174169 = 174242
  • 151 + 174091 = 174242
  • 163 + 174079 = 174242
  • 181 + 174061 = 174242
  • 193 + 174049 = 174242
  • 223 + 174019 = 174242
  • 463 + 173779 = 174242
  • 499 + 173743 = 174242

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 174,242 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 174242 first appears in π at position 921,222 of the decimal expansion (the 921,222ordinal-suffix:nd 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.
