Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1124, here are decompositions:
- 7 + 1117 = 1124
- 31 + 1093 = 1124
- 37 + 1087 = 1124
- 61 + 1063 = 1124
- 73 + 1051 = 1124
- 103 + 1021 = 1124
- 127 + 997 = 1124
- 157 + 967 = 1124
Showing the first eight; more decompositions exist.
