Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020216, here are decompositions:

53 + 1020163 = 1020216
59 + 1020157 = 1020216
73 + 1020143 = 1020216
79 + 1020137 = 1020216
103 + 1020113 = 1020216
107 + 1020109 = 1020216
137 + 1020079 = 1020216
139 + 1020077 = 1020216

Showing the first eight; more decompositions exist.
