Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491060, here are decompositions:

19 + 491041 = 491060
67 + 490993 = 491060
103 + 490957 = 491060
109 + 490951 = 491060
139 + 490921 = 491060
211 + 490849 = 491060
223 + 490837 = 491060
277 + 490783 = 491060

Showing the first eight; more decompositions exist.
