Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556272, here are decompositions:

5 + 556267 = 556272
11 + 556261 = 556272
19 + 556253 = 556272
29 + 556243 = 556272
43 + 556229 = 556272
53 + 556219 = 556272
61 + 556211 = 556272
113 + 556159 = 556272

Showing the first eight; more decompositions exist.
