Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490908, here are decompositions:

17 + 490891 = 490908
31 + 490877 = 490908
59 + 490849 = 490908
71 + 490837 = 490908
79 + 490829 = 490908
137 + 490771 = 490908
139 + 490769 = 490908
167 + 490741 = 490908

Showing the first eight; more decompositions exist.
