Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1154, here are decompositions:
- 3 + 1151 = 1154
- 31 + 1123 = 1154
- 37 + 1117 = 1154
- 61 + 1093 = 1154
- 67 + 1087 = 1154
- 103 + 1051 = 1154
- 157 + 997 = 1154
- 163 + 991 = 1154
Showing the first eight; more decompositions exist.
