Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561936, here are decompositions:

5 + 561931 = 561936
13 + 561923 = 561936
19 + 561917 = 561936
29 + 561907 = 561936
97 + 561839 = 561936
107 + 561829 = 561936
127 + 561809 = 561936
139 + 561797 = 561936

Showing the first eight; more decompositions exist.
