Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530494, here are decompositions:

  • 7 + 31530487 = 31530494
  • 43 + 31530451 = 31530494
  • 103 + 31530391 = 31530494
  • 283 + 31530211 = 31530494
  • 313 + 31530181 = 31530494
  • 397 + 31530097 = 31530494
  • 433 + 31530061 = 31530494
  • 571 + 31529923 = 31530494

Showing the first eight; more decompositions exist.
