Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29870, here are decompositions:

  • 3 + 29867 = 29870
  • 7 + 29863 = 29870
  • 19 + 29851 = 29870
  • 37 + 29833 = 29870
  • 67 + 29803 = 29870
  • 109 + 29761 = 29870
  • 199 + 29671 = 29870
  • 229 + 29641 = 29870

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29870 first appears in π at position 202,216 of the decimal expansion (the 202,216ordinal-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.
