Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560536, here are decompositions:

3 + 31560533 = 31560536
13 + 31560523 = 31560536
37 + 31560499 = 31560536
67 + 31560469 = 31560536
103 + 31560433 = 31560536
193 + 31560343 = 31560536
229 + 31560307 = 31560536
439 + 31560097 = 31560536

Showing the first eight; more decompositions exist.
