Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536260, here are decompositions:

37 + 31536223 = 31536260
73 + 31536187 = 31536260
163 + 31536097 = 31536260
199 + 31536061 = 31536260
211 + 31536049 = 31536260
241 + 31536019 = 31536260
277 + 31535983 = 31536260
313 + 31535947 = 31536260

Showing the first eight; more decompositions exist.
