Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470690, here are decompositions:

37 + 470653 = 470690
43 + 470647 = 470690
97 + 470593 = 470690
139 + 470551 = 470690
151 + 470539 = 470690
229 + 470461 = 470690
277 + 470413 = 470690
331 + 470359 = 470690

Showing the first eight; more decompositions exist.
