Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585676, here are decompositions:
- 13 + 31585663 = 31585676
- 79 + 31585597 = 31585676
- 97 + 31585579 = 31585676
- 127 + 31585549 = 31585676
- 139 + 31585537 = 31585676
- 223 + 31585453 = 31585676
- 229 + 31585447 = 31585676
- 277 + 31585399 = 31585676
Showing the first eight; more decompositions exist.
