Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529298, here are decompositions:
- 19 + 31529279 = 31529298
- 29 + 31529269 = 31529298
- 41 + 31529257 = 31529298
- 79 + 31529219 = 31529298
- 131 + 31529167 = 31529298
- 149 + 31529149 = 31529298
- 191 + 31529107 = 31529298
- 211 + 31529087 = 31529298
Showing the first eight; more decompositions exist.
