Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552164, here are decompositions:

37 + 31552127 = 31552164
107 + 31552057 = 31552164
131 + 31552033 = 31552164
167 + 31551997 = 31552164
223 + 31551941 = 31552164
227 + 31551937 = 31552164
263 + 31551901 = 31552164
307 + 31551857 = 31552164

Showing the first eight; more decompositions exist.
