Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511264, here are decompositions:
- 3 + 31511261 = 31511264
- 97 + 31511167 = 31511264
- 193 + 31511071 = 31511264
- 223 + 31511041 = 31511264
- 271 + 31510993 = 31511264
- 307 + 31510957 = 31511264
- 331 + 31510933 = 31511264
- 373 + 31510891 = 31511264
Showing the first eight; more decompositions exist.
