Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657226, here are decompositions:

5 + 8657221 = 8657226
103 + 8657123 = 8657226
157 + 8657069 = 8657226
173 + 8657053 = 8657226
293 + 8656933 = 8657226
307 + 8656919 = 8657226
379 + 8656847 = 8657226
397 + 8656829 = 8657226

Showing the first eight; more decompositions exist.
