Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102104, here are decompositions:

  • 3 + 102101 = 102104
  • 43 + 102061 = 102104
  • 61 + 102043 = 102104
  • 73 + 102031 = 102104
  • 103 + 102001 = 102104
  • 127 + 101977 = 102104
  • 241 + 101863 = 102104
  • 271 + 101833 = 102104

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 102,104 and was likely granted around 1870.

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

Position in π

The digit sequence 102104 first appears in π at position 886,181 of the decimal expansion (the 886,181ordinal-suffix:st 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.
