Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517654, here are decompositions:

  • 13 + 31517641 = 31517654
  • 37 + 31517617 = 31517654
  • 67 + 31517587 = 31517654
  • 97 + 31517557 = 31517654
  • 127 + 31517527 = 31517654
  • 163 + 31517491 = 31517654
  • 241 + 31517413 = 31517654
  • 457 + 31517197 = 31517654

Showing the first eight; more decompositions exist.
