Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545830, here are decompositions:

  • 3 + 545827 = 545830
  • 41 + 545789 = 545830
  • 71 + 545759 = 545830
  • 83 + 545747 = 545830
  • 107 + 545723 = 545830
  • 167 + 545663 = 545830
  • 179 + 545651 = 545830
  • 251 + 545579 = 545830

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 545,830 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 545830 first appears in π at position 773,957 of the decimal expansion (the 773,957ordinal-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.
