Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30080, here are decompositions:

  • 67 + 30013 = 30080
  • 97 + 29983 = 30080
  • 163 + 29917 = 30080
  • 199 + 29881 = 30080
  • 229 + 29851 = 30080
  • 277 + 29803 = 30080
  • 397 + 29683 = 30080
  • 409 + 29671 = 30080

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30080 first appears in π at position 16,702 of the decimal expansion (the 16,702ordinal-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.
