Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560436, here are decompositions:

3 + 31560433 = 31560436
29 + 31560407 = 31560436
53 + 31560383 = 31560436
137 + 31560299 = 31560436
197 + 31560239 = 31560436
263 + 31560173 = 31560436
389 + 31560047 = 31560436
587 + 31559849 = 31560436

Showing the first eight; more decompositions exist.
