Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542204, here are decompositions:
- 7 + 31542197 = 31542204
- 41 + 31542163 = 31542204
- 101 + 31542103 = 31542204
- 137 + 31542067 = 31542204
- 167 + 31542037 = 31542204
- 173 + 31542031 = 31542204
- 181 + 31542023 = 31542204
- 191 + 31542013 = 31542204
Showing the first eight; more decompositions exist.
