Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1264, here are decompositions:
- 5 + 1259 = 1264
- 41 + 1223 = 1264
- 47 + 1217 = 1264
- 71 + 1193 = 1264
- 83 + 1181 = 1264
- 101 + 1163 = 1264
- 113 + 1151 = 1264
- 167 + 1097 = 1264
Showing the first eight; more decompositions exist.
