Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490808, here are decompositions:

37 + 490771 = 490808
67 + 490741 = 490808
181 + 490627 = 490808
229 + 490579 = 490808
271 + 490537 = 490808
349 + 490459 = 490808
499 + 490309 = 490808
541 + 490267 = 490808

Showing the first eight; more decompositions exist.
