Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78646, here are decompositions:
- 3 + 78643 = 78646
- 23 + 78623 = 78646
- 53 + 78593 = 78646
- 107 + 78539 = 78646
- 137 + 78509 = 78646
- 149 + 78497 = 78646
- 167 + 78479 = 78646
- 179 + 78467 = 78646
Showing the first eight; more decompositions exist.
