Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490730, here are decompositions:

67 + 490663 = 490730
103 + 490627 = 490730
139 + 490591 = 490730
151 + 490579 = 490730
157 + 490573 = 490730
181 + 490549 = 490730
193 + 490537 = 490730
211 + 490519 = 490730

Showing the first eight; more decompositions exist.
