Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553438, here are decompositions:

5 + 553433 = 553438
227 + 553211 = 553438
257 + 553181 = 553438
401 + 553037 = 553438
467 + 552971 = 553438
521 + 552917 = 553438
617 + 552821 = 553438
647 + 552791 = 553438

Showing the first eight; more decompositions exist.
