Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564126, here are decompositions:
- 23 + 31564103 = 31564126
- 47 + 31564079 = 31564126
- 137 + 31563989 = 31564126
- 173 + 31563953 = 31564126
- 179 + 31563947 = 31564126
- 197 + 31563929 = 31564126
- 227 + 31563899 = 31564126
- 263 + 31563863 = 31564126
Showing the first eight; more decompositions exist.
