Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4050, here are decompositions:

  • 23 + 4027 = 4050
  • 29 + 4021 = 4050
  • 31 + 4019 = 4050
  • 37 + 4013 = 4050
  • 43 + 4007 = 4050
  • 47 + 4003 = 4050
  • 61 + 3989 = 4050
  • 83 + 3967 = 4050

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): B7 (3951.1 Hz, +43¢)
  • Scientific pitch (C4 = 256 Hz): C8 (4096 Hz, -20¢)
  • Baroque pitch (A4 = 415 Hz): C8 (3948.2 Hz, +44¢)
Position in π

The digit sequence 4050 first appears in π at position 21,002 of the decimal expansion (the 21,002ordinal-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.
