Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585250, here are decompositions:
- 61 + 31585189 = 31585250
- 79 + 31585171 = 31585250
- 157 + 31585093 = 31585250
- 283 + 31584967 = 31585250
- 349 + 31584901 = 31585250
- 397 + 31584853 = 31585250
- 421 + 31584829 = 31585250
- 547 + 31584703 = 31585250
Showing the first eight; more decompositions exist.
