Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550406, here are decompositions:

37 + 550369 = 550406
97 + 550309 = 550406
127 + 550279 = 550406
139 + 550267 = 550406
193 + 550213 = 550406
229 + 550177 = 550406
277 + 550129 = 550406
379 + 550027 = 550406

Showing the first eight; more decompositions exist.
