Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526904, here are decompositions:

  • 5 + 31526899 = 31526904
  • 11 + 31526893 = 31526904
  • 23 + 31526881 = 31526904
  • 41 + 31526863 = 31526904
  • 113 + 31526791 = 31526904
  • 127 + 31526777 = 31526904
  • 131 + 31526773 = 31526904
  • 151 + 31526753 = 31526904

Showing the first eight; more decompositions exist.
