Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542202, here are decompositions:
- 5 + 31542197 = 31542202
- 53 + 31542149 = 31542202
- 89 + 31542113 = 31542202
- 179 + 31542023 = 31542202
- 191 + 31542011 = 31542202
- 269 + 31541933 = 31542202
- 311 + 31541891 = 31542202
- 509 + 31541693 = 31542202
Showing the first eight; more decompositions exist.
