Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39908, here are decompositions:
- 7 + 39901 = 39908
- 31 + 39877 = 39908
- 61 + 39847 = 39908
- 67 + 39841 = 39908
- 79 + 39829 = 39908
- 109 + 39799 = 39908
- 139 + 39769 = 39908
- 181 + 39727 = 39908
Showing the first eight; more decompositions exist.
