Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526966, here are decompositions:

  • 13 + 31526953 = 31526966
  • 67 + 31526899 = 31526966
  • 73 + 31526893 = 31526966
  • 103 + 31526863 = 31526966
  • 157 + 31526809 = 31526966
  • 193 + 31526773 = 31526966
  • 277 + 31526689 = 31526966
  • 349 + 31526617 = 31526966

Showing the first eight; more decompositions exist.
