Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68360, here are decompositions:
- 31 + 68329 = 68360
- 79 + 68281 = 68360
- 151 + 68209 = 68360
- 199 + 68161 = 68360
- 307 + 68053 = 68360
- 337 + 68023 = 68360
- 367 + 67993 = 68360
- 373 + 67987 = 68360
Showing the first eight; more decompositions exist.
