Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1126, here are decompositions:
- 3 + 1123 = 1126
- 17 + 1109 = 1126
- 23 + 1103 = 1126
- 29 + 1097 = 1126
- 107 + 1019 = 1126
- 113 + 1013 = 1126
- 149 + 977 = 1126
- 173 + 953 = 1126
Showing the first eight; more decompositions exist.
