Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490860, here are decompositions:

11 + 490849 = 490860
23 + 490837 = 490860
31 + 490829 = 490860
89 + 490771 = 490860
127 + 490733 = 490860
163 + 490697 = 490860
197 + 490663 = 490860
199 + 490661 = 490860

Showing the first eight; more decompositions exist.
