Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536464, here are decompositions:

61 + 31536403 = 31536464
67 + 31536397 = 31536464
73 + 31536391 = 31536464
103 + 31536361 = 31536464
151 + 31536313 = 31536464
241 + 31536223 = 31536464
277 + 31536187 = 31536464
367 + 31536097 = 31536464

Showing the first eight; more decompositions exist.
