Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29918, here are decompositions:

  • 37 + 29881 = 29918
  • 67 + 29851 = 29918
  • 157 + 29761 = 29918
  • 277 + 29641 = 29918
  • 307 + 29611 = 29918
  • 331 + 29587 = 29918
  • 337 + 29581 = 29918
  • 349 + 29569 = 29918

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29918 first appears in π at position 122,882 of the decimal expansion (the 122,882ordinal-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.
