Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78426, here are decompositions:
- 59 + 78367 = 78426
- 79 + 78347 = 78426
- 109 + 78317 = 78426
- 149 + 78277 = 78426
- 167 + 78259 = 78426
- 193 + 78233 = 78426
- 197 + 78229 = 78426
- 223 + 78203 = 78426
Showing the first eight; more decompositions exist.
