Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505542, here are decompositions:

  • 5 + 505537 = 505542
  • 19 + 505523 = 505542
  • 29 + 505513 = 505542
  • 31 + 505511 = 505542
  • 41 + 505501 = 505542
  • 61 + 505481 = 505542
  • 73 + 505469 = 505542
  • 83 + 505459 = 505542

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 505,542 and was likely granted around 1893.

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

Position in π

The digit sequence 505542 first appears in π at position 555,703 of the decimal expansion (the 555,703ordinal-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.
