Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641956, here are decompositions:

7 + 8641949 = 8641956
47 + 8641909 = 8641956
73 + 8641883 = 8641956
83 + 8641873 = 8641956
137 + 8641819 = 8641956
139 + 8641817 = 8641956
149 + 8641807 = 8641956
173 + 8641783 = 8641956

Showing the first eight; more decompositions exist.
