Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39892, here are decompositions:
- 5 + 39887 = 39892
- 23 + 39869 = 39892
- 29 + 39863 = 39892
- 53 + 39839 = 39892
- 71 + 39821 = 39892
- 101 + 39791 = 39892
- 113 + 39779 = 39892
- 131 + 39761 = 39892
Showing the first eight; more decompositions exist.
