Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471490, here are decompositions:

3 + 471487 = 471490
23 + 471467 = 471490
83 + 471407 = 471490
101 + 471389 = 471490
137 + 471353 = 471490
191 + 471299 = 471490
281 + 471209 = 471490
311 + 471179 = 471490

Showing the first eight; more decompositions exist.
