Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616942, here are decompositions:

23 + 8616919 = 8616942
29 + 8616913 = 8616942
31 + 8616911 = 8616942
41 + 8616901 = 8616942
73 + 8616869 = 8616942
83 + 8616859 = 8616942
109 + 8616833 = 8616942
179 + 8616763 = 8616942

Showing the first eight; more decompositions exist.
