Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548978, here are decompositions:

109 + 548869 = 548978
127 + 548851 = 548978
151 + 548827 = 548978
229 + 548749 = 548978
271 + 548707 = 548978
307 + 548671 = 548978
349 + 548629 = 548978
421 + 548557 = 548978

Showing the first eight; more decompositions exist.
