Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453108, here are decompositions:

  • 131 + 31452977 = 31453108
  • 257 + 31452851 = 31453108
  • 359 + 31452749 = 31453108
  • 389 + 31452719 = 31453108
  • 431 + 31452677 = 31453108
  • 509 + 31452599 = 31453108
  • 521 + 31452587 = 31453108
  • 569 + 31452539 = 31453108

Showing the first eight; more decompositions exist.
