Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574036, here are decompositions:

  • 37 + 31573999 = 31574036
  • 79 + 31573957 = 31574036
  • 283 + 31573753 = 31574036
  • 397 + 31573639 = 31574036
  • 409 + 31573627 = 31574036
  • 523 + 31573513 = 31574036
  • 643 + 31573393 = 31574036
  • 673 + 31573363 = 31574036

Showing the first eight; more decompositions exist.
