Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560482, here are decompositions:

13 + 31560469 = 31560482
139 + 31560343 = 31560482
409 + 31560073 = 31560482
463 + 31560019 = 31560482
571 + 31559911 = 31560482
631 + 31559851 = 31560482
661 + 31559821 = 31560482
673 + 31559809 = 31560482

Showing the first eight; more decompositions exist.
