Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560396, here are decompositions:

5 + 31560391 = 31560396
13 + 31560383 = 31560396
53 + 31560343 = 31560396
89 + 31560307 = 31560396
97 + 31560299 = 31560396
103 + 31560293 = 31560396
149 + 31560247 = 31560396
157 + 31560239 = 31560396

Showing the first eight; more decompositions exist.
