Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560498, here are decompositions:

29 + 31560469 = 31560498
61 + 31560437 = 31560498
97 + 31560401 = 31560498
107 + 31560391 = 31560498
157 + 31560341 = 31560498
191 + 31560307 = 31560498
199 + 31560299 = 31560498
251 + 31560247 = 31560498

Showing the first eight; more decompositions exist.
