Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16558, here are decompositions:

  • 5 + 16553 = 16558
  • 11 + 16547 = 16558
  • 29 + 16529 = 16558
  • 71 + 16487 = 16558
  • 107 + 16451 = 16558
  • 131 + 16427 = 16558
  • 137 + 16421 = 16558
  • 197 + 16361 = 16558

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16558 first appears in π at position 27,142 of the decimal expansion (the 27,142ordinal-suffix:nd 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.
