Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38660, here are decompositions:
- 7 + 38653 = 38660
- 31 + 38629 = 38660
- 67 + 38593 = 38660
- 103 + 38557 = 38660
- 199 + 38461 = 38660
- 211 + 38449 = 38660
- 229 + 38431 = 38660
- 283 + 38377 = 38660
Showing the first eight; more decompositions exist.
