Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1186, here are decompositions:
- 5 + 1181 = 1186
- 23 + 1163 = 1186
- 83 + 1103 = 1186
- 89 + 1097 = 1186
- 137 + 1049 = 1186
- 167 + 1019 = 1186
- 173 + 1013 = 1186
- 233 + 953 = 1186
Showing the first eight; more decompositions exist.
