Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639006, here are decompositions:

7 + 8638999 = 8639006
73 + 8638933 = 8639006
97 + 8638909 = 8639006
139 + 8638867 = 8639006
157 + 8638849 = 8639006
163 + 8638843 = 8639006
199 + 8638807 = 8639006
373 + 8638633 = 8639006

Showing the first eight; more decompositions exist.
