Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39216, here are decompositions:
- 7 + 39209 = 39216
- 17 + 39199 = 39216
- 53 + 39163 = 39216
- 59 + 39157 = 39216
- 83 + 39133 = 39216
- 97 + 39119 = 39216
- 103 + 39113 = 39216
- 109 + 39107 = 39216
Showing the first eight; more decompositions exist.
