Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1118, here are decompositions:
- 31 + 1087 = 1118
- 67 + 1051 = 1118
- 79 + 1039 = 1118
- 97 + 1021 = 1118
- 109 + 1009 = 1118
- 127 + 991 = 1118
- 151 + 967 = 1118
- 181 + 937 = 1118
Showing the first eight; more decompositions exist.
