Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669156, here are decompositions:

43 + 8669113 = 8669156
73 + 8669083 = 8669156
163 + 8668993 = 8669156
283 + 8668873 = 8669156
373 + 8668783 = 8669156
547 + 8668609 = 8669156
607 + 8668549 = 8669156
673 + 8668483 = 8669156

Showing the first eight; more decompositions exist.
