Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556766, here are decompositions:

3 + 556763 = 556766
13 + 556753 = 556766
43 + 556723 = 556766
73 + 556693 = 556766
79 + 556687 = 556766
127 + 556639 = 556766
139 + 556627 = 556766
157 + 556609 = 556766

Showing the first eight; more decompositions exist.
