Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536342, here are decompositions:

29 + 31536313 = 31536342
139 + 31536203 = 31536342
181 + 31536161 = 31536342
241 + 31536101 = 31536342
281 + 31536061 = 31536342
293 + 31536049 = 31536342
359 + 31535983 = 31536342
401 + 31535941 = 31536342

Showing the first eight; more decompositions exist.
