Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490812, here are decompositions:

29 + 490783 = 490812
41 + 490771 = 490812
43 + 490769 = 490812
71 + 490741 = 490812
79 + 490733 = 490812
149 + 490663 = 490812
151 + 490661 = 490812
181 + 490631 = 490812

Showing the first eight; more decompositions exist.
