Also seen as
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.
