Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 554640, here are decompositions:

7 + 554633 = 554640
13 + 554627 = 554640
29 + 554611 = 554640
43 + 554597 = 554640
67 + 554573 = 554640
71 + 554569 = 554640
109 + 554531 = 554640
113 + 554527 = 554640

Showing the first eight; more decompositions exist.
