Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38964, here are decompositions:
- 5 + 38959 = 38964
- 11 + 38953 = 38964
- 31 + 38933 = 38964
- 41 + 38923 = 38964
- 43 + 38921 = 38964
- 47 + 38917 = 38964
- 61 + 38903 = 38964
- 73 + 38891 = 38964
Showing the first eight; more decompositions exist.
