Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13558, here are decompositions:

  • 5 + 13553 = 13558
  • 59 + 13499 = 13558
  • 71 + 13487 = 13558
  • 89 + 13469 = 13558
  • 101 + 13457 = 13558
  • 107 + 13451 = 13558
  • 137 + 13421 = 13558
  • 191 + 13367 = 13558

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13558 first appears in π at position 48,928 of the decimal expansion (the 48,928ordinal-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.
