Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536274, here are decompositions:

47 + 31536227 = 31536274
71 + 31536203 = 31536274
113 + 31536161 = 31536274
173 + 31536101 = 31536274
257 + 31536017 = 31536274
293 + 31535981 = 31536274
443 + 31535831 = 31536274
521 + 31535753 = 31536274

Showing the first eight; more decompositions exist.
