Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552146, here are decompositions:

7 + 31552139 = 31552146
19 + 31552127 = 31552146
89 + 31552057 = 31552146
97 + 31552049 = 31552146
113 + 31552033 = 31552146
127 + 31552019 = 31552146
149 + 31551997 = 31552146
167 + 31551979 = 31552146

Showing the first eight; more decompositions exist.
