Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80530, here are decompositions:

  • 3 + 80527 = 80530
  • 17 + 80513 = 80530
  • 41 + 80489 = 80530
  • 59 + 80471 = 80530
  • 83 + 80447 = 80530
  • 101 + 80429 = 80530
  • 167 + 80363 = 80530
  • 251 + 80279 = 80530

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80530 first appears in π at position 165,303 of the decimal expansion (the 165,303ordinal-suffix:rd 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.
