Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644612, here are decompositions:

3 + 8644609 = 8644612
5 + 8644607 = 8644612
59 + 8644553 = 8644612
83 + 8644529 = 8644612
101 + 8644511 = 8644612
113 + 8644499 = 8644612
173 + 8644439 = 8644612
281 + 8644331 = 8644612

Showing the first eight; more decompositions exist.
