Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645926, here are decompositions:

137 + 8645789 = 8645926
167 + 8645759 = 8645926
197 + 8645729 = 8645926
239 + 8645687 = 8645926
257 + 8645669 = 8645926
269 + 8645657 = 8645926
293 + 8645633 = 8645926
347 + 8645579 = 8645926

Showing the first eight; more decompositions exist.
