Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560764, here are decompositions:

7 + 31560757 = 31560764
13 + 31560751 = 31560764
61 + 31560703 = 31560764
181 + 31560583 = 31560764
223 + 31560541 = 31560764
241 + 31560523 = 31560764
331 + 31560433 = 31560764
373 + 31560391 = 31560764

Showing the first eight; more decompositions exist.
