Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526630, here are decompositions:

  • 13 + 31526617 = 31526630
  • 67 + 31526563 = 31526630
  • 97 + 31526533 = 31526630
  • 103 + 31526527 = 31526630
  • 127 + 31526503 = 31526630
  • 199 + 31526431 = 31526630
  • 211 + 31526419 = 31526630
  • 241 + 31526389 = 31526630

Showing the first eight; more decompositions exist.
