Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641992, here are decompositions:

5 + 8641987 = 8641992
43 + 8641949 = 8641992
83 + 8641909 = 8641992
101 + 8641891 = 8641992
109 + 8641883 = 8641992
173 + 8641819 = 8641992
211 + 8641781 = 8641992
251 + 8641741 = 8641992

Showing the first eight; more decompositions exist.
