Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30550, here are decompositions:

  • 11 + 30539 = 30550
  • 41 + 30509 = 30550
  • 53 + 30497 = 30550
  • 59 + 30491 = 30550
  • 83 + 30467 = 30550
  • 101 + 30449 = 30550
  • 227 + 30323 = 30550
  • 257 + 30293 = 30550

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30550 first appears in π at position 182,456 of the decimal expansion (the 182,456ordinal-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.
