Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536222, here are decompositions:

19 + 31536203 = 31536222
61 + 31536161 = 31536222
173 + 31536049 = 31536222
239 + 31535983 = 31536222
241 + 31535981 = 31536222
281 + 31535941 = 31536222
283 + 31535939 = 31536222
313 + 31535909 = 31536222

Showing the first eight; more decompositions exist.
