Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561948, here are decompositions:

5 + 561943 = 561948
17 + 561931 = 561948
31 + 561917 = 561948
41 + 561907 = 561948
109 + 561839 = 561948
139 + 561809 = 561948
151 + 561797 = 561948
181 + 561767 = 561948

Showing the first eight; more decompositions exist.
