Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642954, here are decompositions:

3 + 8642951 = 8642954
7 + 8642947 = 8642954
43 + 8642911 = 8642954
97 + 8642857 = 8642954
181 + 8642773 = 8642954
193 + 8642761 = 8642954
373 + 8642581 = 8642954
421 + 8642533 = 8642954

Showing the first eight; more decompositions exist.
