Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564328, here are decompositions:
- 7 + 31564321 = 31564328
- 67 + 31564261 = 31564328
- 79 + 31564249 = 31564328
- 157 + 31564171 = 31564328
- 181 + 31564147 = 31564328
- 199 + 31564129 = 31564328
- 277 + 31564051 = 31564328
- 349 + 31563979 = 31564328
Showing the first eight; more decompositions exist.
