Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556942, here are decompositions:

3 + 556939 = 556942
11 + 556931 = 556942
59 + 556883 = 556942
83 + 556859 = 556942
101 + 556841 = 556942
131 + 556811 = 556942
149 + 556793 = 556942
173 + 556769 = 556942

Showing the first eight; more decompositions exist.
