Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470990, here are decompositions:

31 + 470959 = 470990
43 + 470947 = 470990
103 + 470887 = 470990
109 + 470881 = 470990
127 + 470863 = 470990
199 + 470791 = 470990
211 + 470779 = 470990
241 + 470749 = 470990

Showing the first eight; more decompositions exist.
