Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41640, here are decompositions:

13 + 41627 = 41640
19 + 41621 = 41640
23 + 41617 = 41640
29 + 41611 = 41640
31 + 41609 = 41640
37 + 41603 = 41640
43 + 41597 = 41640
47 + 41593 = 41640

Showing the first eight; more decompositions exist.
