Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675138, here are decompositions:

79 + 8675059 = 8675138
127 + 8675011 = 8675138
211 + 8674927 = 8675138
271 + 8674867 = 8675138
379 + 8674759 = 8675138
457 + 8674681 = 8675138
601 + 8674537 = 8675138
607 + 8674531 = 8675138

Showing the first eight; more decompositions exist.
