Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8318, here are decompositions:
- 7 + 8311 = 8318
- 31 + 8287 = 8318
- 97 + 8221 = 8318
- 109 + 8209 = 8318
- 127 + 8191 = 8318
- 139 + 8179 = 8318
- 151 + 8167 = 8318
- 157 + 8161 = 8318
Showing the first eight; more decompositions exist.
