Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15524, here are decompositions:

  • 13 + 15511 = 15524
  • 31 + 15493 = 15524
  • 73 + 15451 = 15524
  • 97 + 15427 = 15524
  • 151 + 15373 = 15524
  • 163 + 15361 = 15524
  • 193 + 15331 = 15524
  • 211 + 15313 = 15524

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15524 first appears in π at position 174,121 of the decimal expansion (the 174,121ordinal-suffix:st 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.
