Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490844, here are decompositions:

7 + 490837 = 490844
61 + 490783 = 490844
73 + 490771 = 490844
103 + 490741 = 490844
181 + 490663 = 490844
271 + 490573 = 490844
307 + 490537 = 490844
577 + 490267 = 490844

Showing the first eight; more decompositions exist.
