Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550538, here are decompositions:

7 + 550531 = 550538
19 + 550519 = 550538
67 + 550471 = 550538
97 + 550441 = 550538
229 + 550309 = 550538
271 + 550267 = 550538
349 + 550189 = 550538
409 + 550129 = 550538

Showing the first eight; more decompositions exist.
