Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453048, here are decompositions:

  • 71 + 31452977 = 31453048
  • 197 + 31452851 = 31453048
  • 317 + 31452731 = 31453048
  • 449 + 31452599 = 31453048
  • 461 + 31452587 = 31453048
  • 509 + 31452539 = 31453048
  • 521 + 31452527 = 31453048
  • 587 + 31452461 = 31453048

Showing the first eight; more decompositions exist.
