Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599724, here are decompositions:

  • 17 + 31599707 = 31599724
  • 41 + 31599683 = 31599724
  • 53 + 31599671 = 31599724
  • 71 + 31599653 = 31599724
  • 113 + 31599611 = 31599724
  • 173 + 31599551 = 31599724
  • 293 + 31599431 = 31599724
  • 383 + 31599341 = 31599724

Showing the first eight; more decompositions exist.
