Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556782, here are decompositions:

13 + 556769 = 556782
19 + 556763 = 556782
29 + 556753 = 556782
41 + 556741 = 556782
59 + 556723 = 556782
73 + 556709 = 556782
89 + 556693 = 556782
103 + 556679 = 556782

Showing the first eight; more decompositions exist.
