Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642136, here are decompositions:

17 + 8642119 = 8642136
29 + 8642107 = 8642136
37 + 8642099 = 8642136
59 + 8642077 = 8642136
73 + 8642063 = 8642136
79 + 8642057 = 8642136
103 + 8642033 = 8642136
109 + 8642027 = 8642136

Showing the first eight; more decompositions exist.
