Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642046, here are decompositions:

13 + 8642033 = 8642046
19 + 8642027 = 8642046
43 + 8642003 = 8642046
59 + 8641987 = 8642046
89 + 8641957 = 8642046
97 + 8641949 = 8642046
137 + 8641909 = 8642046
163 + 8641883 = 8642046

Showing the first eight; more decompositions exist.
