Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567850, here are decompositions:

31 + 31567819 = 31567850
37 + 31567813 = 31567850
109 + 31567741 = 31567850
151 + 31567699 = 31567850
157 + 31567693 = 31567850
163 + 31567687 = 31567850
229 + 31567621 = 31567850
337 + 31567513 = 31567850

Showing the first eight; more decompositions exist.
