Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544516, here are decompositions:

  • 7 + 31544509 = 31544516
  • 193 + 31544323 = 31544516
  • 337 + 31544179 = 31544516
  • 349 + 31544167 = 31544516
  • 439 + 31544077 = 31544516
  • 463 + 31544053 = 31544516
  • 613 + 31543903 = 31544516
  • 643 + 31543873 = 31544516

Showing the first eight; more decompositions exist.
