Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988, here are decompositions:
- 5 + 983 = 988
- 11 + 977 = 988
- 17 + 971 = 988
- 41 + 947 = 988
- 47 + 941 = 988
- 59 + 929 = 988
- 101 + 887 = 988
- 107 + 881 = 988
Showing the first eight; more decompositions exist.
