Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672478, here are decompositions:

7 + 8672471 = 8672478
37 + 8672441 = 8672478
71 + 8672407 = 8672478
97 + 8672381 = 8672478
131 + 8672347 = 8672478
181 + 8672297 = 8672478
211 + 8672267 = 8672478
239 + 8672239 = 8672478

Showing the first eight; more decompositions exist.
