Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621046, here are decompositions:

29 + 8621017 = 8621046
37 + 8621009 = 8621046
53 + 8620993 = 8621046
73 + 8620973 = 8621046
97 + 8620949 = 8621046
103 + 8620943 = 8621046
149 + 8620897 = 8621046
173 + 8620873 = 8621046

Showing the first eight; more decompositions exist.
