Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526570, here are decompositions:

  • 7 + 31526563 = 31526570
  • 37 + 31526533 = 31526570
  • 43 + 31526527 = 31526570
  • 67 + 31526503 = 31526570
  • 73 + 31526497 = 31526570
  • 139 + 31526431 = 31526570
  • 151 + 31526419 = 31526570
  • 181 + 31526389 = 31526570

Showing the first eight; more decompositions exist.
