Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536632, here are decompositions:

3 + 31536629 = 31536632
19 + 31536613 = 31536632
103 + 31536529 = 31536632
151 + 31536481 = 31536632
229 + 31536403 = 31536632
241 + 31536391 = 31536632
271 + 31536361 = 31536632
409 + 31536223 = 31536632

Showing the first eight; more decompositions exist.
