Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526756, here are decompositions:

  • 3 + 31526753 = 31526756
  • 7 + 31526749 = 31526756
  • 43 + 31526713 = 31526756
  • 67 + 31526689 = 31526756
  • 109 + 31526647 = 31526756
  • 139 + 31526617 = 31526756
  • 193 + 31526563 = 31526756
  • 223 + 31526533 = 31526756

Showing the first eight; more decompositions exist.
