Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560024, here are decompositions:

5 + 31560019 = 31560024
43 + 31559981 = 31560024
47 + 31559977 = 31560024
73 + 31559951 = 31560024
113 + 31559911 = 31560024
163 + 31559861 = 31560024
173 + 31559851 = 31560024
191 + 31559833 = 31560024

Showing the first eight; more decompositions exist.
