Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1116, here are decompositions:
- 7 + 1109 = 1116
- 13 + 1103 = 1116
- 19 + 1097 = 1116
- 23 + 1093 = 1116
- 29 + 1087 = 1116
- 47 + 1069 = 1116
- 53 + 1063 = 1116
- 67 + 1049 = 1116
Showing the first eight; more decompositions exist.
