Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552038, here are decompositions:

5 + 31552033 = 31552038
19 + 31552019 = 31552038
41 + 31551997 = 31552038
59 + 31551979 = 31552038
61 + 31551977 = 31552038
79 + 31551959 = 31552038
97 + 31551941 = 31552038
101 + 31551937 = 31552038

Showing the first eight; more decompositions exist.
