Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552206, here are decompositions:

13 + 31552193 = 31552206
67 + 31552139 = 31552206
79 + 31552127 = 31552206
137 + 31552069 = 31552206
149 + 31552057 = 31552206
157 + 31552049 = 31552206
173 + 31552033 = 31552206
227 + 31551979 = 31552206

Showing the first eight; more decompositions exist.
