Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536406, here are decompositions:

3 + 31536403 = 31536406
23 + 31536383 = 31536406
47 + 31536359 = 31536406
53 + 31536353 = 31536406
59 + 31536347 = 31536406
113 + 31536293 = 31536406
179 + 31536227 = 31536406
353 + 31536053 = 31536406

Showing the first eight; more decompositions exist.
