Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718380, here are decompositions:

3 + 8718377 = 8718380
31 + 8718349 = 8718380
37 + 8718343 = 8718380
67 + 8718313 = 8718380
79 + 8718301 = 8718380
103 + 8718277 = 8718380
109 + 8718271 = 8718380
163 + 8718217 = 8718380

Showing the first eight; more decompositions exist.
