Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561876, here are decompositions:

37 + 561839 = 561876
47 + 561829 = 561876
67 + 561809 = 561876
79 + 561797 = 561876
89 + 561787 = 561876
109 + 561767 = 561876
163 + 561713 = 561876
173 + 561703 = 561876

Showing the first eight; more decompositions exist.
