Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984, here are decompositions:

  • 7 + 977 = 984
  • 13 + 971 = 984
  • 17 + 967 = 984
  • 31 + 953 = 984
  • 37 + 947 = 984
  • 43 + 941 = 984
  • 47 + 937 = 984
  • 73 + 911 = 984

Showing the first eight; more decompositions exist.
