Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536238, here are decompositions:

11 + 31536227 = 31536238
137 + 31536101 = 31536238
257 + 31535981 = 31536238
359 + 31535879 = 31536238
491 + 31535747 = 31536238
521 + 31535717 = 31536238
557 + 31535681 = 31536238
599 + 31535639 = 31536238

Showing the first eight; more decompositions exist.
