Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641932, here are decompositions:

23 + 8641909 = 8641932
41 + 8641891 = 8641932
59 + 8641873 = 8641932
113 + 8641819 = 8641932
149 + 8641783 = 8641932
151 + 8641781 = 8641932
191 + 8641741 = 8641932
199 + 8641733 = 8641932

Showing the first eight; more decompositions exist.
