Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642626, here are decompositions:

59 + 8642567 = 8642626
107 + 8642519 = 8642626
137 + 8642489 = 8642626
173 + 8642453 = 8642626
197 + 8642429 = 8642626
389 + 8642237 = 8642626
467 + 8642159 = 8642626
479 + 8642147 = 8642626

Showing the first eight; more decompositions exist.
