Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538978, here are decompositions:

47 + 538931 = 538978
101 + 538877 = 538978
107 + 538871 = 538978
137 + 538841 = 538978
149 + 538829 = 538978
179 + 538799 = 538978
227 + 538751 = 538978
239 + 538739 = 538978

Showing the first eight; more decompositions exist.
