Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19508, here are decompositions:

  • 7 + 19501 = 19508
  • 19 + 19489 = 19508
  • 31 + 19477 = 19508
  • 37 + 19471 = 19508
  • 61 + 19447 = 19508
  • 67 + 19441 = 19508
  • 79 + 19429 = 19508
  • 127 + 19381 = 19508

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): D♯10 (19912.1 Hz, -35¢)
  • Scientific pitch (C4 = 256 Hz): D♯10 (19484 Hz, +2¢)
  • Baroque pitch (A4 = 415 Hz): E10 (19897.5 Hz, -34¢)
Position in π

The digit sequence 19508 first appears in π at position 53,146 of the decimal expansion (the 53,146ordinal-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.
