Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550398, here are decompositions:

19 + 550379 = 550398
29 + 550369 = 550398
47 + 550351 = 550398
61 + 550337 = 550398
89 + 550309 = 550398
109 + 550289 = 550398
131 + 550267 = 550398
157 + 550241 = 550398

Showing the first eight; more decompositions exist.
