Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531018, here are decompositions:

  • 17 + 31531001 = 31531018
  • 41 + 31530977 = 31531018
  • 59 + 31530959 = 31531018
  • 191 + 31530827 = 31531018
  • 317 + 31530701 = 31531018
  • 359 + 31530659 = 31531018
  • 401 + 31530617 = 31531018
  • 521 + 31530497 = 31531018

Showing the first eight; more decompositions exist.
