Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542120, here are decompositions:

  • 3 + 542117 = 542120
  • 37 + 542083 = 542120
  • 67 + 542053 = 542120
  • 97 + 542023 = 542120
  • 127 + 541993 = 542120
  • 193 + 541927 = 542120
  • 283 + 541837 = 542120
  • 349 + 541771 = 542120

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 542,120 and was likely granted around 1895.

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

Position in π

The digit sequence 542120 first appears in π at position 173,673 of the decimal expansion (the 173,673ordinal-suffix:rd 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.
