Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556956, here are decompositions:

13 + 556943 = 556956
17 + 556939 = 556956
73 + 556883 = 556956
89 + 556867 = 556956
97 + 556859 = 556956
107 + 556849 = 556956
137 + 556819 = 556956
139 + 556817 = 556956

Showing the first eight; more decompositions exist.
