Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39312, here are decompositions:
- 11 + 39301 = 39312
- 19 + 39293 = 39312
- 61 + 39251 = 39312
- 71 + 39241 = 39312
- 73 + 39239 = 39312
- 79 + 39233 = 39312
- 83 + 39229 = 39312
- 103 + 39209 = 39312
Showing the first eight; more decompositions exist.
