Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550490, here are decompositions:

19 + 550471 = 550490
43 + 550447 = 550490
139 + 550351 = 550490
181 + 550309 = 550490
211 + 550279 = 550490
223 + 550267 = 550490
277 + 550213 = 550490
313 + 550177 = 550490

Showing the first eight; more decompositions exist.
