Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638002, here are decompositions:

11 + 8637991 = 8638002
29 + 8637973 = 8638002
59 + 8637943 = 8638002
73 + 8637929 = 8638002
173 + 8637829 = 8638002
181 + 8637821 = 8638002
211 + 8637791 = 8638002
223 + 8637779 = 8638002

Showing the first eight; more decompositions exist.
