Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30556, here are decompositions:

  • 3 + 30553 = 30556
  • 17 + 30539 = 30556
  • 47 + 30509 = 30556
  • 59 + 30497 = 30556
  • 89 + 30467 = 30556
  • 107 + 30449 = 30556
  • 167 + 30389 = 30556
  • 233 + 30323 = 30556

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30556 first appears in π at position 92,903 of the decimal expansion (the 92,903ordinal-suffix:rd 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.
