Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049690, here are decompositions:

3 + 1049687 = 1049690
7 + 1049683 = 1049690
13 + 1049677 = 1049690
67 + 1049623 = 1049690
79 + 1049611 = 1049690
157 + 1049533 = 1049690
163 + 1049527 = 1049690
181 + 1049509 = 1049690

Showing the first eight; more decompositions exist.
