Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11248, here are decompositions:

  • 5 + 11243 = 11248
  • 71 + 11177 = 11248
  • 89 + 11159 = 11248
  • 131 + 11117 = 11248
  • 179 + 11069 = 11248
  • 191 + 11057 = 11248
  • 269 + 10979 = 11248
  • 311 + 10937 = 11248

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): F9 (11175.3 Hz, +11¢)
  • Scientific pitch (C4 = 256 Hz): F9 (10935 Hz, +49¢ — about midway to F♯9)
  • Baroque pitch (A4 = 415 Hz): F♯9 (11167.1 Hz, +12¢)
Position in π

The digit sequence 11248 first appears in π at position 44,177 of the decimal expansion (the 44,177ordinal-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.
