Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637318, here are decompositions:

7 + 8637311 = 8637318
17 + 8637301 = 8637318
29 + 8637289 = 8637318
61 + 8637257 = 8637318
71 + 8637247 = 8637318
139 + 8637179 = 8637318
167 + 8637151 = 8637318
199 + 8637119 = 8637318

Showing the first eight; more decompositions exist.
