Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1304, here are decompositions:
- 3 + 1301 = 1304
- 7 + 1297 = 1304
- 13 + 1291 = 1304
- 67 + 1237 = 1304
- 73 + 1231 = 1304
- 103 + 1201 = 1304
- 151 + 1153 = 1304
- 181 + 1123 = 1304
Showing the first eight; more decompositions exist.
