Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526672, here are decompositions:

  • 3 + 31526669 = 31526672
  • 109 + 31526563 = 31526672
  • 139 + 31526533 = 31526672
  • 241 + 31526431 = 31526672
  • 283 + 31526389 = 31526672
  • 313 + 31526359 = 31526672
  • 433 + 31526239 = 31526672
  • 691 + 31525981 = 31526672

Showing the first eight; more decompositions exist.
