Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550988, here are decompositions:

19 + 550969 = 550988
37 + 550951 = 550988
79 + 550909 = 550988
127 + 550861 = 550988
157 + 550831 = 550988
199 + 550789 = 550988
271 + 550717 = 550988
331 + 550657 = 550988

Showing the first eight; more decompositions exist.
