Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542176, here are decompositions:
- 13 + 31542163 = 31542176
- 73 + 31542103 = 31542176
- 109 + 31542067 = 31542176
- 139 + 31542037 = 31542176
- 163 + 31542013 = 31542176
- 199 + 31541977 = 31542176
- 277 + 31541899 = 31542176
- 283 + 31541893 = 31542176
Showing the first eight; more decompositions exist.
