Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637280, here are decompositions:

17 + 8637263 = 8637280
23 + 8637257 = 8637280
53 + 8637227 = 8637280
101 + 8637179 = 8637280
149 + 8637131 = 8637280
173 + 8637107 = 8637280
227 + 8637053 = 8637280
263 + 8637017 = 8637280

Showing the first eight; more decompositions exist.
