Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38646, here are decompositions:
- 7 + 38639 = 38646
- 17 + 38629 = 38646
- 37 + 38609 = 38646
- 43 + 38603 = 38646
- 53 + 38593 = 38646
- 79 + 38567 = 38646
- 89 + 38557 = 38646
- 103 + 38543 = 38646
Showing the first eight; more decompositions exist.
