Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552122, here are decompositions:

53 + 31552069 = 31552122
73 + 31552049 = 31552122
89 + 31552033 = 31552122
103 + 31552019 = 31552122
163 + 31551959 = 31552122
181 + 31551941 = 31552122
263 + 31551859 = 31552122
269 + 31551853 = 31552122

Showing the first eight; more decompositions exist.
