Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488490, here are decompositions:

17 + 488473 = 488490
31 + 488459 = 488490
71 + 488419 = 488490
73 + 488417 = 488490
83 + 488407 = 488490
89 + 488401 = 488490
109 + 488381 = 488490
137 + 488353 = 488490

Showing the first eight; more decompositions exist.
