Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552050, here are decompositions:

17 + 31552033 = 31552050
31 + 31552019 = 31552050
53 + 31551997 = 31552050
71 + 31551979 = 31552050
73 + 31551977 = 31552050
109 + 31551941 = 31552050
113 + 31551937 = 31552050
149 + 31551901 = 31552050

Showing the first eight; more decompositions exist.
