Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545556, here are decompositions:
- 149 + 31545407 = 31545556
- 227 + 31545329 = 31545556
- 233 + 31545323 = 31545556
- 239 + 31545317 = 31545556
- 257 + 31545299 = 31545556
- 269 + 31545287 = 31545556
- 587 + 31544969 = 31545556
- 593 + 31544963 = 31545556
Showing the first eight; more decompositions exist.
