Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490720, here are decompositions:

23 + 490697 = 490720
59 + 490661 = 490720
89 + 490631 = 490720
101 + 490619 = 490720
149 + 490571 = 490720
179 + 490541 = 490720
227 + 490493 = 490720
239 + 490481 = 490720

Showing the first eight; more decompositions exist.
