Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78310, here are decompositions:
- 3 + 78307 = 78310
- 107 + 78203 = 78310
- 131 + 78179 = 78310
- 137 + 78173 = 78310
- 173 + 78137 = 78310
- 251 + 78059 = 78310
- 269 + 78041 = 78310
- 293 + 78017 = 78310
Showing the first eight; more decompositions exist.
