Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536330, here are decompositions:

17 + 31536313 = 31536330
37 + 31536293 = 31536330
43 + 31536287 = 31536330
103 + 31536227 = 31536330
107 + 31536223 = 31536330
127 + 31536203 = 31536330
229 + 31536101 = 31536330
233 + 31536097 = 31536330

Showing the first eight; more decompositions exist.
