Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506922, here are decompositions:
- 11 + 31506911 = 31506922
- 101 + 31506821 = 31506922
- 113 + 31506809 = 31506922
- 131 + 31506791 = 31506922
- 173 + 31506749 = 31506922
- 179 + 31506743 = 31506922
- 233 + 31506689 = 31506922
- 281 + 31506641 = 31506922
Showing the first eight; more decompositions exist.
