Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644902, here are decompositions:

29 + 8644873 = 8644902
41 + 8644861 = 8644902
59 + 8644843 = 8644902
103 + 8644799 = 8644902
131 + 8644771 = 8644902
151 + 8644751 = 8644902
173 + 8644729 = 8644902
179 + 8644723 = 8644902

Showing the first eight; more decompositions exist.
