Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574050, here are decompositions:

3 + 31574047 = 31574050
29 + 31574021 = 31574050
83 + 31573967 = 31574050
89 + 31573961 = 31574050
191 + 31573859 = 31574050
197 + 31573853 = 31574050
227 + 31573823 = 31574050
257 + 31573793 = 31574050

Showing the first eight; more decompositions exist.
