Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1172, here are decompositions:
- 19 + 1153 = 1172
- 43 + 1129 = 1172
- 79 + 1093 = 1172
- 103 + 1069 = 1172
- 109 + 1063 = 1172
- 139 + 1033 = 1172
- 151 + 1021 = 1172
- 163 + 1009 = 1172
Showing the first eight; more decompositions exist.
