Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15502, here are decompositions:

  • 5 + 15497 = 15502
  • 29 + 15473 = 15502
  • 41 + 15461 = 15502
  • 59 + 15443 = 15502
  • 89 + 15413 = 15502
  • 101 + 15401 = 15502
  • 173 + 15329 = 15502
  • 233 + 15269 = 15502

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15502 first appears in π at position 77,948 of the decimal expansion (the 77,948ordinal-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.
