Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29880, here are decompositions:

  • 7 + 29873 = 29880
  • 13 + 29867 = 29880
  • 17 + 29863 = 29880
  • 29 + 29851 = 29880
  • 43 + 29837 = 29880
  • 47 + 29833 = 29880
  • 61 + 29819 = 29880
  • 127 + 29753 = 29880

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29880 first appears in π at position 487,318 of the decimal expansion (the 487,318ordinal-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.
