Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526528, here are decompositions:

  • 31 + 31526497 = 31526528
  • 97 + 31526431 = 31526528
  • 109 + 31526419 = 31526528
  • 139 + 31526389 = 31526528
  • 157 + 31526371 = 31526528
  • 211 + 31526317 = 31526528
  • 307 + 31526221 = 31526528
  • 331 + 31526197 = 31526528

Showing the first eight; more decompositions exist.
