Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538430, here are decompositions:

  • 7 + 538423 = 538430
  • 19 + 538411 = 538430
  • 31 + 538399 = 538430
  • 73 + 538357 = 538430
  • 97 + 538333 = 538430
  • 127 + 538303 = 538430
  • 163 + 538267 = 538430
  • 181 + 538249 = 538430

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 538,430 and was likely granted around 1894.

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

Position in π

The digit sequence 538430 first appears in π at position 377,562 of the decimal expansion (the 377,562ordinal-suffix:nd 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.
