Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560592, here are decompositions:

3 + 31560589 = 31560592
5 + 31560587 = 31560592
23 + 31560569 = 31560592
59 + 31560533 = 31560592
83 + 31560509 = 31560592
191 + 31560401 = 31560592
251 + 31560341 = 31560592
293 + 31560299 = 31560592

Showing the first eight; more decompositions exist.
