Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563116, here are decompositions:

  • 43 + 31563073 = 31563116
  • 73 + 31563043 = 31563116
  • 103 + 31563013 = 31563116
  • 157 + 31562959 = 31563116
  • 199 + 31562917 = 31563116
  • 337 + 31562779 = 31563116
  • 349 + 31562767 = 31563116
  • 379 + 31562737 = 31563116

Showing the first eight; more decompositions exist.
