Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542246, here are decompositions:
- 13 + 31542233 = 31542246
- 17 + 31542229 = 31542246
- 83 + 31542163 = 31542246
- 97 + 31542149 = 31542246
- 163 + 31542083 = 31542246
- 179 + 31542067 = 31542246
- 223 + 31542023 = 31542246
- 233 + 31542013 = 31542246
Showing the first eight; more decompositions exist.
