Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622950, here are decompositions:

3 + 31622947 = 31622950
11 + 31622939 = 31622950
17 + 31622933 = 31622950
113 + 31622837 = 31622950
173 + 31622777 = 31622950
251 + 31622699 = 31622950
257 + 31622693 = 31622950
263 + 31622687 = 31622950

Showing the first eight; more decompositions exist.
