Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720474, here are decompositions:

3 + 8720471 = 8720474
43 + 8720431 = 8720474
67 + 8720407 = 8720474
127 + 8720347 = 8720474
157 + 8720317 = 8720474
163 + 8720311 = 8720474
193 + 8720281 = 8720474
241 + 8720233 = 8720474

Showing the first eight; more decompositions exist.
