Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560036, here are decompositions:

7 + 31560029 = 31560036
17 + 31560019 = 31560036
47 + 31559989 = 31560036
59 + 31559977 = 31560036
223 + 31559813 = 31560036
227 + 31559809 = 31560036
317 + 31559719 = 31560036
337 + 31559699 = 31560036

Showing the first eight; more decompositions exist.
