Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536340, here are decompositions:
- 47 + 31536293 = 31536340
- 53 + 31536287 = 31536340
- 113 + 31536227 = 31536340
- 137 + 31536203 = 31536340
- 179 + 31536161 = 31536340
- 239 + 31536101 = 31536340
- 359 + 31535981 = 31536340
- 401 + 31535939 = 31536340
Showing the first eight; more decompositions exist.
