Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552182, here are decompositions:

43 + 31552139 = 31552182
113 + 31552069 = 31552182
149 + 31552033 = 31552182
163 + 31552019 = 31552182
223 + 31551959 = 31552182
241 + 31551941 = 31552182
281 + 31551901 = 31552182
379 + 31551803 = 31552182

Showing the first eight; more decompositions exist.
