Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556788, here are decompositions:

7 + 556781 = 556788
19 + 556769 = 556788
47 + 556741 = 556788
61 + 556727 = 556788
79 + 556709 = 556788
97 + 556691 = 556788
101 + 556687 = 556788
109 + 556679 = 556788

Showing the first eight; more decompositions exist.
