Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637270, here are decompositions:

7 + 8637263 = 8637270
13 + 8637257 = 8637270
17 + 8637253 = 8637270
23 + 8637247 = 8637270
43 + 8637227 = 8637270
67 + 8637203 = 8637270
107 + 8637163 = 8637270
137 + 8637133 = 8637270

Showing the first eight; more decompositions exist.
