Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548636, here are decompositions:

  • 17 + 31548619 = 31548636
  • 23 + 31548613 = 31548636
  • 43 + 31548593 = 31548636
  • 59 + 31548577 = 31548636
  • 73 + 31548563 = 31548636
  • 89 + 31548547 = 31548636
  • 103 + 31548533 = 31548636
  • 109 + 31548527 = 31548636

Showing the first eight; more decompositions exist.
