Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78338, here are decompositions:
- 31 + 78307 = 78338
- 37 + 78301 = 78338
- 61 + 78277 = 78338
- 79 + 78259 = 78338
- 97 + 78241 = 78338
- 109 + 78229 = 78338
- 181 + 78157 = 78338
- 199 + 78139 = 78338
Showing the first eight; more decompositions exist.
