Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1108, here are decompositions:
- 5 + 1103 = 1108
- 11 + 1097 = 1108
- 17 + 1091 = 1108
- 47 + 1061 = 1108
- 59 + 1049 = 1108
- 89 + 1019 = 1108
- 131 + 977 = 1108
- 137 + 971 = 1108
Showing the first eight; more decompositions exist.
