Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542200, here are decompositions:
- 3 + 31542197 = 31542200
- 37 + 31542163 = 31542200
- 97 + 31542103 = 31542200
- 163 + 31542037 = 31542200
- 199 + 31542001 = 31542200
- 211 + 31541989 = 31542200
- 223 + 31541977 = 31542200
- 229 + 31541971 = 31542200
Showing the first eight; more decompositions exist.
