Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82012, here are decompositions:

  • 3 + 82009 = 82012
  • 5 + 82007 = 82012
  • 41 + 81971 = 82012
  • 59 + 81953 = 82012
  • 83 + 81929 = 82012
  • 113 + 81899 = 82012
  • 173 + 81839 = 82012
  • 239 + 81773 = 82012

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 82012 first appears in π at position 127,043 of the decimal expansion (the 127,043ordinal-suffix:rd 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.
