Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642774, here are decompositions:

13 + 8642761 = 8642774
193 + 8642581 = 8642774
241 + 8642533 = 8642774
307 + 8642467 = 8642774
577 + 8642197 = 8642774
601 + 8642173 = 8642774
787 + 8641987 = 8642774
883 + 8641891 = 8642774

Showing the first eight; more decompositions exist.
