Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163308, here are decompositions:
- 59 + 163249 = 163308
- 97 + 163211 = 163308
- 109 + 163199 = 163308
- 127 + 163181 = 163308
- 137 + 163171 = 163308
- 139 + 163169 = 163308
- 157 + 163151 = 163308
- 179 + 163129 = 163308
Showing the first eight; more decompositions exist.
