Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1168, here are decompositions:
- 5 + 1163 = 1168
- 17 + 1151 = 1168
- 59 + 1109 = 1168
- 71 + 1097 = 1168
- 107 + 1061 = 1168
- 137 + 1031 = 1168
- 149 + 1019 = 1168
- 191 + 977 = 1168
Showing the first eight; more decompositions exist.
