Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1248, here are decompositions:
- 11 + 1237 = 1248
- 17 + 1231 = 1248
- 19 + 1229 = 1248
- 31 + 1217 = 1248
- 47 + 1201 = 1248
- 61 + 1187 = 1248
- 67 + 1181 = 1248
- 97 + 1151 = 1248
Showing the first eight; more decompositions exist.
