Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642746, here are decompositions:

23 + 8642723 = 8642746
113 + 8642633 = 8642746
179 + 8642567 = 8642746
227 + 8642519 = 8642746
239 + 8642507 = 8642746
257 + 8642489 = 8642746
293 + 8642453 = 8642746
317 + 8642429 = 8642746

Showing the first eight; more decompositions exist.
