Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536232, here are decompositions:
- 5 + 31536227 = 31536232
- 29 + 31536203 = 31536232
- 71 + 31536161 = 31536232
- 131 + 31536101 = 31536232
- 179 + 31536053 = 31536232
- 251 + 31535981 = 31536232
- 293 + 31535939 = 31536232
- 353 + 31535879 = 31536232
Showing the first eight; more decompositions exist.
