Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552086, here are decompositions:

17 + 31552069 = 31552086
29 + 31552057 = 31552086
37 + 31552049 = 31552086
53 + 31552033 = 31552086
67 + 31552019 = 31552086
89 + 31551997 = 31552086
107 + 31551979 = 31552086
109 + 31551977 = 31552086

Showing the first eight; more decompositions exist.
