Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718474, here are decompositions:

5 + 8718469 = 8718474
13 + 8718461 = 8718474
43 + 8718431 = 8718474
47 + 8718427 = 8718474
67 + 8718407 = 8718474
73 + 8718401 = 8718474
97 + 8718377 = 8718474
131 + 8718343 = 8718474

Showing the first eight; more decompositions exist.
