Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39918, here are decompositions:
- 17 + 39901 = 39918
- 31 + 39887 = 39918
- 41 + 39877 = 39918
- 61 + 39857 = 39918
- 71 + 39847 = 39918
- 79 + 39839 = 39918
- 89 + 39829 = 39918
- 97 + 39821 = 39918
Showing the first eight; more decompositions exist.
