Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526910, here are decompositions:

  • 7 + 31526903 = 31526910
  • 11 + 31526899 = 31526910
  • 17 + 31526893 = 31526910
  • 29 + 31526881 = 31526910
  • 31 + 31526879 = 31526910
  • 47 + 31526863 = 31526910
  • 101 + 31526809 = 31526910
  • 137 + 31526773 = 31526910

Showing the first eight; more decompositions exist.
