Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490182, here are decompositions:

  • 83 + 31490099 = 31490182
  • 89 + 31490093 = 31490182
  • 233 + 31489949 = 31490182
  • 239 + 31489943 = 31490182
  • 263 + 31489919 = 31490182
  • 281 + 31489901 = 31490182
  • 431 + 31489751 = 31490182
  • 461 + 31489721 = 31490182

Showing the first eight; more decompositions exist.
