Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527460, here are decompositions:
- 47 + 31527413 = 31527460
- 53 + 31527407 = 31527460
- 71 + 31527389 = 31527460
- 137 + 31527323 = 31527460
- 149 + 31527311 = 31527460
- 227 + 31527233 = 31527460
- 269 + 31527191 = 31527460
- 311 + 31527149 = 31527460
Showing the first eight; more decompositions exist.
