Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470978, here are decompositions:

19 + 470959 = 470978
31 + 470947 = 470978
37 + 470941 = 470978
97 + 470881 = 470978
199 + 470779 = 470978
229 + 470749 = 470978
331 + 470647 = 470978
379 + 470599 = 470978

Showing the first eight; more decompositions exist.
