Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637226, here are decompositions:

23 + 8637203 = 8637226
47 + 8637179 = 8637226
107 + 8637119 = 8637226
167 + 8637059 = 8637226
173 + 8637053 = 8637226
239 + 8636987 = 8637226
317 + 8636909 = 8637226
467 + 8636759 = 8637226

Showing the first eight; more decompositions exist.
