Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542134, here are decompositions:
- 31 + 31542103 = 31542134
- 67 + 31542067 = 31542134
- 97 + 31542037 = 31542134
- 103 + 31542031 = 31542134
- 157 + 31541977 = 31542134
- 163 + 31541971 = 31542134
- 241 + 31541893 = 31542134
- 277 + 31541857 = 31542134
Showing the first eight; more decompositions exist.
