Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 479978, here are decompositions:

7 + 479971 = 479978
97 + 479881 = 479978
139 + 479839 = 479978
157 + 479821 = 479978
181 + 479797 = 479978
229 + 479749 = 479978
277 + 479701 = 479978
349 + 479629 = 479978

Showing the first eight; more decompositions exist.
