Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536564, here are decompositions:

13 + 31536551 = 31536564
43 + 31536521 = 31536564
83 + 31536481 = 31536564
167 + 31536397 = 31536564
173 + 31536391 = 31536564
181 + 31536383 = 31536564
211 + 31536353 = 31536564
251 + 31536313 = 31536564

Showing the first eight; more decompositions exist.
