Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637304, here are decompositions:

3 + 8637301 = 8637304
41 + 8637263 = 8637304
47 + 8637257 = 8637304
101 + 8637203 = 8637304
173 + 8637131 = 8637304
197 + 8637107 = 8637304
251 + 8637053 = 8637304
317 + 8636987 = 8637304

Showing the first eight; more decompositions exist.
