Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 994, here are decompositions:

  • 3 + 991 = 994
  • 11 + 983 = 994
  • 17 + 977 = 994
  • 23 + 971 = 994
  • 41 + 953 = 994
  • 47 + 947 = 994
  • 53 + 941 = 994
  • 83 + 911 = 994

Showing the first eight; more decompositions exist.
