Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490316, here are decompositions:

  • 17 + 31490299 = 31490316
  • 19 + 31490297 = 31490316
  • 29 + 31490287 = 31490316
  • 59 + 31490257 = 31490316
  • 79 + 31490237 = 31490316
  • 89 + 31490227 = 31490316
  • 127 + 31490189 = 31490316
  • 167 + 31490149 = 31490316

Showing the first eight; more decompositions exist.
