Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 936640, here are decompositions:

41 + 936599 = 936640
53 + 936587 = 936640
83 + 936557 = 936640
101 + 936539 = 936640
113 + 936527 = 936640
227 + 936413 = 936640
233 + 936407 = 936640
239 + 936401 = 936640

Showing the first eight; more decompositions exist.
