Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553668, here are decompositions:

19 + 553649 = 553668
41 + 553627 = 553668
61 + 553607 = 553668
67 + 553601 = 553668
79 + 553589 = 553668
107 + 553561 = 553668
139 + 553529 = 553668
151 + 553517 = 553668

Showing the first eight; more decompositions exist.
