Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61558, here are decompositions:

  • 5 + 61553 = 61558
  • 11 + 61547 = 61558
  • 47 + 61511 = 61558
  • 71 + 61487 = 61558
  • 89 + 61469 = 61558
  • 149 + 61409 = 61558
  • 179 + 61379 = 61558
  • 227 + 61331 = 61558

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61558 first appears in π at position 200,298 of the decimal expansion (the 200,298ordinal-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.
