Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536646, here are decompositions:

17 + 31536629 = 31536646
107 + 31536539 = 31536646
263 + 31536383 = 31536646
293 + 31536353 = 31536646
353 + 31536293 = 31536646
359 + 31536287 = 31536646
419 + 31536227 = 31536646
443 + 31536203 = 31536646

Showing the first eight; more decompositions exist.
