Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166078, here are decompositions:

  • 47 + 166031 = 166078
  • 131 + 165947 = 166078
  • 137 + 165941 = 166078
  • 191 + 165887 = 166078
  • 359 + 165719 = 166078
  • 461 + 165617 = 166078
  • 467 + 165611 = 166078
  • 491 + 165587 = 166078

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 166,078 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 166078 first appears in π at position 117,287 of the decimal expansion (the 117,287ordinal-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.
