Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023216, here are decompositions:

13 + 1023203 = 1023216
17 + 1023199 = 1023216
43 + 1023173 = 1023216
53 + 1023163 = 1023216
83 + 1023133 = 1023216
109 + 1023107 = 1023216
137 + 1023079 = 1023216
149 + 1023067 = 1023216

Showing the first eight; more decompositions exist.
