Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529412, here are decompositions:
- 53 + 31529359 = 31529412
- 59 + 31529353 = 31529412
- 139 + 31529273 = 31529412
- 163 + 31529249 = 31529412
- 193 + 31529219 = 31529412
- 199 + 31529213 = 31529412
- 263 + 31529149 = 31529412
- 331 + 31529081 = 31529412
Showing the first eight; more decompositions exist.
