Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1198, here are decompositions:
- 5 + 1193 = 1198
- 11 + 1187 = 1198
- 17 + 1181 = 1198
- 47 + 1151 = 1198
- 89 + 1109 = 1198
- 101 + 1097 = 1198
- 107 + 1091 = 1198
- 137 + 1061 = 1198
Showing the first eight; more decompositions exist.
