Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78422, here are decompositions:
- 139 + 78283 = 78422
- 163 + 78259 = 78422
- 181 + 78241 = 78422
- 193 + 78229 = 78422
- 229 + 78193 = 78422
- 283 + 78139 = 78422
- 373 + 78049 = 78422
- 439 + 77983 = 78422
Showing the first eight; more decompositions exist.
