Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598550, here are decompositions:

  • 7 + 31598543 = 31598550
  • 13 + 31598537 = 31598550
  • 29 + 31598521 = 31598550
  • 31 + 31598519 = 31598550
  • 37 + 31598513 = 31598550
  • 101 + 31598449 = 31598550
  • 127 + 31598423 = 31598550
  • 131 + 31598419 = 31598550

Showing the first eight; more decompositions exist.
