Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645226, here are decompositions:

47 + 8645179 = 8645226
103 + 8645123 = 8645226
113 + 8645113 = 8645226
173 + 8645053 = 8645226
179 + 8645047 = 8645226
197 + 8645029 = 8645226
263 + 8644963 = 8645226
269 + 8644957 = 8645226

Showing the first eight; more decompositions exist.
