Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620334, here are decompositions:

  • 17 + 31620317 = 31620334
  • 71 + 31620263 = 31620334
  • 131 + 31620203 = 31620334
  • 167 + 31620167 = 31620334
  • 227 + 31620107 = 31620334
  • 353 + 31619981 = 31620334
  • 491 + 31619843 = 31620334
  • 563 + 31619771 = 31620334

Showing the first eight; more decompositions exist.
