Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649892, here are decompositions:

5 + 8649887 = 8649892
11 + 8649881 = 8649892
23 + 8649869 = 8649892
89 + 8649803 = 8649892
101 + 8649791 = 8649892
131 + 8649761 = 8649892
263 + 8649629 = 8649892
269 + 8649623 = 8649892

Showing the first eight; more decompositions exist.
