Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536396, here are decompositions:

5 + 31536391 = 31536396
13 + 31536383 = 31536396
37 + 31536359 = 31536396
43 + 31536353 = 31536396
83 + 31536313 = 31536396
103 + 31536293 = 31536396
109 + 31536287 = 31536396
173 + 31536223 = 31536396

Showing the first eight; more decompositions exist.
