Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 554518, here are decompositions:

71 + 554447 = 554518
101 + 554417 = 554518
281 + 554237 = 554518
311 + 554207 = 554518
347 + 554171 = 554518
389 + 554129 = 554518
401 + 554117 = 554518
431 + 554087 = 554518

Showing the first eight; more decompositions exist.
