Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552156, here are decompositions:

17 + 31552139 = 31552156
29 + 31552127 = 31552156
107 + 31552049 = 31552156
137 + 31552019 = 31552156
179 + 31551977 = 31552156
197 + 31551959 = 31552156
353 + 31551803 = 31552156
557 + 31551599 = 31552156

Showing the first eight; more decompositions exist.
