Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78682, here are decompositions:
- 29 + 78653 = 78682
- 59 + 78623 = 78682
- 89 + 78593 = 78682
- 113 + 78569 = 78682
- 173 + 78509 = 78682
- 281 + 78401 = 78682
- 449 + 78233 = 78682
- 479 + 78203 = 78682
Showing the first eight; more decompositions exist.
