Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 554428, here are decompositions:

11 + 554417 = 554428
191 + 554237 = 554428
239 + 554189 = 554428
257 + 554171 = 554428
311 + 554117 = 554428
467 + 553961 = 554428
509 + 553919 = 554428
617 + 553811 = 554428

Showing the first eight; more decompositions exist.
