Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645002, here are decompositions:

11 + 8644991 = 8645002
53 + 8644949 = 8645002
83 + 8644919 = 8645002
89 + 8644913 = 8645002
251 + 8644751 = 8645002
449 + 8644553 = 8645002
491 + 8644511 = 8645002
503 + 8644499 = 8645002

Showing the first eight; more decompositions exist.
