Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453634, here are decompositions:

  • 127 + 31453507 = 31453634
  • 151 + 31453483 = 31453634
  • 241 + 31453393 = 31453634
  • 313 + 31453321 = 31453634
  • 367 + 31453267 = 31453634
  • 463 + 31453171 = 31453634
  • 613 + 31453021 = 31453634
  • 661 + 31452973 = 31453634

Showing the first eight; more decompositions exist.
