Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30256, here are decompositions:

  • 3 + 30253 = 30256
  • 53 + 30203 = 30256
  • 59 + 30197 = 30256
  • 137 + 30119 = 30256
  • 167 + 30089 = 30256
  • 197 + 30059 = 30256
  • 227 + 30029 = 30256
  • 383 + 29873 = 30256

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30256 first appears in π at position 41,521 of the decimal expansion (the 41,521ordinal-suffix:st 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.
