Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453490, here are decompositions:

  • 7 + 31453483 = 31453490
  • 43 + 31453447 = 31453490
  • 97 + 31453393 = 31453490
  • 157 + 31453333 = 31453490
  • 223 + 31453267 = 31453490
  • 241 + 31453249 = 31453490
  • 283 + 31453207 = 31453490
  • 331 + 31453159 = 31453490

Showing the first eight; more decompositions exist.
