Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536402, here are decompositions:

5 + 31536397 = 31536402
11 + 31536391 = 31536402
19 + 31536383 = 31536402
41 + 31536361 = 31536402
43 + 31536359 = 31536402
89 + 31536313 = 31536402
109 + 31536293 = 31536402
179 + 31536223 = 31536402

Showing the first eight; more decompositions exist.
