Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109640, here are decompositions:

19 + 109621 = 109640
31 + 109609 = 109640
43 + 109597 = 109640
61 + 109579 = 109640
73 + 109567 = 109640
103 + 109537 = 109640
199 + 109441 = 109640
277 + 109363 = 109640

Showing the first eight; more decompositions exist.
