Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532514, here are decompositions:

  • 7 + 31532507 = 31532514
  • 17 + 31532497 = 31532514
  • 37 + 31532477 = 31532514
  • 113 + 31532401 = 31532514
  • 173 + 31532341 = 31532514
  • 191 + 31532323 = 31532514
  • 311 + 31532203 = 31532514
  • 347 + 31532167 = 31532514

Showing the first eight; more decompositions exist.
