Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666252, here are decompositions:

79 + 8666173 = 8666252
193 + 8666059 = 8666252
229 + 8666023 = 8666252
313 + 8665939 = 8666252
379 + 8665873 = 8666252
601 + 8665651 = 8666252
619 + 8665633 = 8666252
691 + 8665561 = 8666252

Showing the first eight; more decompositions exist.
