Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8683640, here are decompositions:

3 + 8683637 = 8683640
37 + 8683603 = 8683640
109 + 8683531 = 8683640
157 + 8683483 = 8683640
181 + 8683459 = 8683640
313 + 8683327 = 8683640
331 + 8683309 = 8683640
337 + 8683303 = 8683640

Showing the first eight; more decompositions exist.
