Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490830, here are decompositions:

47 + 490783 = 490830
59 + 490771 = 490830
61 + 490769 = 490830
89 + 490741 = 490830
97 + 490733 = 490830
167 + 490663 = 490830
199 + 490631 = 490830
211 + 490619 = 490830

Showing the first eight; more decompositions exist.
