Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12350, here are decompositions:

  • 3 + 12347 = 12350
  • 7 + 12343 = 12350
  • 61 + 12289 = 12350
  • 73 + 12277 = 12350
  • 97 + 12253 = 12350
  • 109 + 12241 = 12350
  • 139 + 12211 = 12350
  • 193 + 12157 = 12350

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): G9 (12543.9 Hz, -27¢)
  • Scientific pitch (C4 = 256 Hz): G9 (12274.1 Hz, +11¢)
  • Baroque pitch (A4 = 415 Hz): G♯9 (12534.7 Hz, -26¢)
Position in π

The digit sequence 12350 first appears in π at position 41,952 of the decimal expansion (the 41,952ordinal-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.
