Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560588, here are decompositions:

5 + 31560583 = 31560588
19 + 31560569 = 31560588
29 + 31560559 = 31560588
47 + 31560541 = 31560588
79 + 31560509 = 31560588
89 + 31560499 = 31560588
151 + 31560437 = 31560588
181 + 31560407 = 31560588

Showing the first eight; more decompositions exist.
