Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564030, here are decompositions:
- 41 + 31563989 = 31564030
- 83 + 31563947 = 31564030
- 89 + 31563941 = 31564030
- 101 + 31563929 = 31564030
- 131 + 31563899 = 31564030
- 149 + 31563881 = 31564030
- 167 + 31563863 = 31564030
- 257 + 31563773 = 31564030
Showing the first eight; more decompositions exist.
