Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550378, here are decompositions:

41 + 550337 = 550378
89 + 550289 = 550378
137 + 550241 = 550378
167 + 550211 = 550378
197 + 550181 = 550378
239 + 550139 = 550378
251 + 550127 = 550378
317 + 550061 = 550378

Showing the first eight; more decompositions exist.
