Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983640, here are decompositions:

23 + 983617 = 983640
43 + 983597 = 983640
59 + 983581 = 983640
61 + 983579 = 983640
83 + 983557 = 983640
107 + 983533 = 983640
109 + 983531 = 983640
113 + 983527 = 983640

Showing the first eight; more decompositions exist.
