Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573682, here are decompositions:

  • 3 + 31573679 = 31573682
  • 43 + 31573639 = 31573682
  • 61 + 31573621 = 31573682
  • 181 + 31573501 = 31573682
  • 421 + 31573261 = 31573682
  • 571 + 31573111 = 31573682
  • 661 + 31573021 = 31573682
  • 733 + 31572949 = 31573682

Showing the first eight; more decompositions exist.
