Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78318, here are decompositions:
- 7 + 78311 = 78318
- 11 + 78307 = 78318
- 17 + 78301 = 78318
- 41 + 78277 = 78318
- 59 + 78259 = 78318
- 89 + 78229 = 78318
- 127 + 78191 = 78318
- 139 + 78179 = 78318
Showing the first eight; more decompositions exist.
