Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498924, here are decompositions:

  • 11 + 31498913 = 31498924
  • 71 + 31498853 = 31498924
  • 113 + 31498811 = 31498924
  • 383 + 31498541 = 31498924
  • 461 + 31498463 = 31498924
  • 503 + 31498421 = 31498924
  • 557 + 31498367 = 31498924
  • 617 + 31498307 = 31498924

Showing the first eight; more decompositions exist.
