Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1063640, here are decompositions:

3 + 1063637 = 1063640
13 + 1063627 = 1063640
31 + 1063609 = 1063640
43 + 1063597 = 1063640
79 + 1063561 = 1063640
139 + 1063501 = 1063640
157 + 1063483 = 1063640
163 + 1063477 = 1063640

Showing the first eight; more decompositions exist.
