Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1234, here are decompositions:

  • 3 + 1231 = 1234
  • 5 + 1229 = 1234
  • 11 + 1223 = 1234
  • 17 + 1217 = 1234
  • 41 + 1193 = 1234
  • 47 + 1187 = 1234
  • 53 + 1181 = 1234
  • 71 + 1163 = 1234

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1234 first appears in π at position 13,807 of the decimal expansion (the 13,807ordinal-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.
