Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016580, here are decompositions:

7 + 1016573 = 1016580
11 + 1016569 = 1016580
13 + 1016567 = 1016580
53 + 1016527 = 1016580
83 + 1016497 = 1016580
127 + 1016453 = 1016580
139 + 1016441 = 1016580
157 + 1016423 = 1016580

Showing the first eight; more decompositions exist.
