Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550978, here are decompositions:

5 + 550973 = 550978
17 + 550961 = 550978
41 + 550937 = 550978
137 + 550841 = 550978
167 + 550811 = 550978
257 + 550721 = 550978
317 + 550661 = 550978
347 + 550631 = 550978

Showing the first eight; more decompositions exist.
