Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550380, here are decompositions:

11 + 550369 = 550380
29 + 550351 = 550380
43 + 550337 = 550380
71 + 550309 = 550380
97 + 550283 = 550380
101 + 550279 = 550380
113 + 550267 = 550380
139 + 550241 = 550380

Showing the first eight; more decompositions exist.
