Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491044, here are decompositions:

3 + 491041 = 491044
5 + 491039 = 491044
41 + 491003 = 491044
53 + 490991 = 491044
107 + 490937 = 491044
131 + 490913 = 491044
167 + 490877 = 491044
311 + 490733 = 491044

Showing the first eight; more decompositions exist.
