Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506438, here are decompositions:

  • 109 + 506329 = 506438
  • 157 + 506281 = 506438
  • 307 + 506131 = 506438
  • 337 + 506101 = 506438
  • 367 + 506071 = 506438
  • 571 + 505867 = 506438
  • 619 + 505819 = 506438
  • 661 + 505777 = 506438

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 506,438 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 506438 first appears in π at position 540,014 of the decimal expansion (the 540,014ordinal-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.
