Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644002, here are decompositions:

5 + 8643997 = 8644002
11 + 8643991 = 8644002
43 + 8643959 = 8644002
61 + 8643941 = 8644002
79 + 8643923 = 8644002
83 + 8643919 = 8644002
109 + 8643893 = 8644002
113 + 8643889 = 8644002

Showing the first eight; more decompositions exist.
