Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550428, here are decompositions:

59 + 550369 = 550428
139 + 550289 = 550428
149 + 550279 = 550428
239 + 550189 = 550428
251 + 550177 = 550428
311 + 550117 = 550428
317 + 550111 = 550428
367 + 550061 = 550428

Showing the first eight; more decompositions exist.
