Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39912, here are decompositions:
- 11 + 39901 = 39912
- 29 + 39883 = 39912
- 43 + 39869 = 39912
- 71 + 39841 = 39912
- 73 + 39839 = 39912
- 83 + 39829 = 39912
- 113 + 39799 = 39912
- 151 + 39761 = 39912
Showing the first eight; more decompositions exist.
