Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526402, here are decompositions:

  • 13 + 31526389 = 31526402
  • 31 + 31526371 = 31526402
  • 43 + 31526359 = 31526402
  • 163 + 31526239 = 31526402
  • 181 + 31526221 = 31526402
  • 211 + 31526191 = 31526402
  • 421 + 31525981 = 31526402
  • 499 + 31525903 = 31526402

Showing the first eight; more decompositions exist.
