Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490134, here are decompositions:

  • 3 + 31490131 = 31490134
  • 41 + 31490093 = 31490134
  • 191 + 31489943 = 31490134
  • 233 + 31489901 = 31490134
  • 251 + 31489883 = 31490134
  • 293 + 31489841 = 31490134
  • 317 + 31489817 = 31490134
  • 383 + 31489751 = 31490134

Showing the first eight; more decompositions exist.
