Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573950, here are decompositions:

19 + 31573931 = 31573950
97 + 31573853 = 31573950
103 + 31573847 = 31573950
127 + 31573823 = 31573950
131 + 31573819 = 31573950
157 + 31573793 = 31573950
193 + 31573757 = 31573950
197 + 31573753 = 31573950

Showing the first eight; more decompositions exist.
