Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5380, here are decompositions:

  • 29 + 5351 = 5380
  • 47 + 5333 = 5380
  • 71 + 5309 = 5380
  • 83 + 5297 = 5380
  • 101 + 5279 = 5380
  • 107 + 5273 = 5380
  • 149 + 5231 = 5380
  • 191 + 5189 = 5380

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): E8 (5274 Hz, +34¢)
  • Scientific pitch (C4 = 256 Hz): F8 (5467.5 Hz, -28¢)
  • Baroque pitch (A4 = 415 Hz): F8 (5270.2 Hz, +36¢)
Position in π

The digit sequence 5380 first appears in π at position 14,079 of the decimal expansion (the 14,079ordinal-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.
