Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548648, here are decompositions:

  • 7 + 31548641 = 31548648
  • 29 + 31548619 = 31548648
  • 71 + 31548577 = 31548648
  • 97 + 31548551 = 31548648
  • 101 + 31548547 = 31548648
  • 127 + 31548521 = 31548648
  • 149 + 31548499 = 31548648
  • 181 + 31548467 = 31548648

Showing the first eight; more decompositions exist.
