Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576250, here are decompositions:
- 19 + 31576231 = 31576250
- 31 + 31576219 = 31576250
- 163 + 31576087 = 31576250
- 241 + 31576009 = 31576250
- 313 + 31575937 = 31576250
- 373 + 31575877 = 31576250
- 421 + 31575829 = 31576250
- 457 + 31575793 = 31576250
Showing the first eight; more decompositions exist.
