Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637380, here are decompositions:

7 + 8637373 = 8637380
43 + 8637337 = 8637380
61 + 8637319 = 8637380
79 + 8637301 = 8637380
127 + 8637253 = 8637380
229 + 8637151 = 8637380
277 + 8637103 = 8637380
313 + 8637067 = 8637380

Showing the first eight; more decompositions exist.
