Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 996, here are decompositions:

  • 5 + 991 = 996
  • 13 + 983 = 996
  • 19 + 977 = 996
  • 29 + 967 = 996
  • 43 + 953 = 996
  • 59 + 937 = 996
  • 67 + 929 = 996
  • 89 + 907 = 996

Showing the first eight; more decompositions exist.
