Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490786, here are decompositions:

3 + 490783 = 490786
17 + 490769 = 490786
53 + 490733 = 490786
89 + 490697 = 490786
167 + 490619 = 490786
227 + 490559 = 490786
293 + 490493 = 490786
419 + 490367 = 490786

Showing the first eight; more decompositions exist.
