Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560582, here are decompositions:

13 + 31560569 = 31560582
23 + 31560559 = 31560582
41 + 31560541 = 31560582
59 + 31560523 = 31560582
73 + 31560509 = 31560582
83 + 31560499 = 31560582
113 + 31560469 = 31560582
149 + 31560433 = 31560582

Showing the first eight; more decompositions exist.
