Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1310, here are decompositions:
- 3 + 1307 = 1310
- 7 + 1303 = 1310
- 13 + 1297 = 1310
- 19 + 1291 = 1310
- 31 + 1279 = 1310
- 61 + 1249 = 1310
- 73 + 1237 = 1310
- 79 + 1231 = 1310
Showing the first eight; more decompositions exist.
