Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568750, here are decompositions:

  • 7 + 31568743 = 31568750
  • 13 + 31568737 = 31568750
  • 139 + 31568611 = 31568750
  • 163 + 31568587 = 31568750
  • 211 + 31568539 = 31568750
  • 223 + 31568527 = 31568750
  • 331 + 31568419 = 31568750
  • 337 + 31568413 = 31568750

Showing the first eight; more decompositions exist.
