Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543842, here are decompositions:

  • 31 + 543811 = 543842
  • 73 + 543769 = 543842
  • 139 + 543703 = 543842
  • 163 + 543679 = 543842
  • 181 + 543661 = 543842
  • 241 + 543601 = 543842
  • 379 + 543463 = 543842
  • 463 + 543379 = 543842

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 543,842 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 543842 first appears in π at position 812,495 of the decimal expansion (the 812,495ordinal-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.
