Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553428, here are decompositions:

11 + 553417 = 553428
17 + 553411 = 553428
59 + 553369 = 553428
149 + 553279 = 553428
151 + 553277 = 553428
179 + 553249 = 553428
199 + 553229 = 553428
257 + 553171 = 553428

Showing the first eight; more decompositions exist.
