Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490984, here are decompositions:

17 + 490967 = 490984
47 + 490937 = 490984
71 + 490913 = 490984
107 + 490877 = 490984
251 + 490733 = 490984
353 + 490631 = 490984
443 + 490541 = 490984
491 + 490493 = 490984

Showing the first eight; more decompositions exist.
