Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567320, here are decompositions:
- 7 + 31567313 = 31567320
- 23 + 31567297 = 31567320
- 41 + 31567279 = 31567320
- 53 + 31567267 = 31567320
- 79 + 31567241 = 31567320
- 89 + 31567231 = 31567320
- 101 + 31567219 = 31567320
- 107 + 31567213 = 31567320
Showing the first eight; more decompositions exist.
