Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15308, here are decompositions:

  • 19 + 15289 = 15308
  • 31 + 15277 = 15308
  • 37 + 15271 = 15308
  • 67 + 15241 = 15308
  • 109 + 15199 = 15308
  • 277 + 15031 = 15308
  • 379 + 14929 = 15308
  • 421 + 14887 = 15308

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15308 first appears in π at position 38,369 of the decimal expansion (the 38,369ordinal-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.
