Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558850, here are decompositions:

3 + 31558847 = 31558850
7 + 31558843 = 31558850
19 + 31558831 = 31558850
31 + 31558819 = 31558850
61 + 31558789 = 31558850
79 + 31558771 = 31558850
109 + 31558741 = 31558850
157 + 31558693 = 31558850

Showing the first eight; more decompositions exist.
