Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536562, here are decompositions:

11 + 31536551 = 31536562
23 + 31536539 = 31536562
41 + 31536521 = 31536562
179 + 31536383 = 31536562
269 + 31536293 = 31536562
359 + 31536203 = 31536562
401 + 31536161 = 31536562
461 + 31536101 = 31536562

Showing the first eight; more decompositions exist.
