Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649802, here are decompositions:

11 + 8649791 = 8649802
41 + 8649761 = 8649802
113 + 8649689 = 8649802
131 + 8649671 = 8649802
173 + 8649629 = 8649802
179 + 8649623 = 8649802
191 + 8649611 = 8649802
269 + 8649533 = 8649802

Showing the first eight; more decompositions exist.
