Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519084, here are decompositions:

  • 11 + 31519073 = 31519084
  • 17 + 31519067 = 31519084
  • 131 + 31518953 = 31519084
  • 257 + 31518827 = 31519084
  • 431 + 31518653 = 31519084
  • 491 + 31518593 = 31519084
  • 563 + 31518521 = 31519084
  • 593 + 31518491 = 31519084

Showing the first eight; more decompositions exist.
