Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536552, here are decompositions:

13 + 31536539 = 31536552
23 + 31536529 = 31536552
31 + 31536521 = 31536552
53 + 31536499 = 31536552
71 + 31536481 = 31536552
149 + 31536403 = 31536552
191 + 31536361 = 31536552
193 + 31536359 = 31536552

Showing the first eight; more decompositions exist.
