Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549842, here are decompositions:

  • 3 + 549839 = 549842
  • 103 + 549739 = 549842
  • 109 + 549733 = 549842
  • 151 + 549691 = 549842
  • 193 + 549649 = 549842
  • 199 + 549643 = 549842
  • 331 + 549511 = 549842
  • 421 + 549421 = 549842

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 549,842 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 549842 first appears in π at position 243,706 of the decimal expansion (the 243,706ordinal-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.
