Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526864, here are decompositions:

  • 73 + 31526791 = 31526864
  • 151 + 31526713 = 31526864
  • 331 + 31526533 = 31526864
  • 337 + 31526527 = 31526864
  • 367 + 31526497 = 31526864
  • 433 + 31526431 = 31526864
  • 547 + 31526317 = 31526864
  • 643 + 31526221 = 31526864

Showing the first eight; more decompositions exist.
