Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556404, here are decompositions:

5 + 556399 = 556404
31 + 556373 = 556404
53 + 556351 = 556404
61 + 556343 = 556404
73 + 556331 = 556404
83 + 556321 = 556404
131 + 556273 = 556404
137 + 556267 = 556404

Showing the first eight; more decompositions exist.
