Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644650, here are decompositions:

17 + 8644633 = 8644650
41 + 8644609 = 8644650
43 + 8644607 = 8644650
97 + 8644553 = 8644650
139 + 8644511 = 8644650
149 + 8644501 = 8644650
151 + 8644499 = 8644650
173 + 8644477 = 8644650

Showing the first eight; more decompositions exist.
