Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536138, here are decompositions:

37 + 31536101 = 31536138
41 + 31536097 = 31536138
89 + 31536049 = 31536138
157 + 31535981 = 31536138
191 + 31535947 = 31536138
197 + 31535941 = 31536138
199 + 31535939 = 31536138
229 + 31535909 = 31536138

Showing the first eight; more decompositions exist.
