Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641962, here are decompositions:

5 + 8641957 = 8641962
13 + 8641949 = 8641962
53 + 8641909 = 8641962
71 + 8641891 = 8641962
79 + 8641883 = 8641962
89 + 8641873 = 8641962
179 + 8641783 = 8641962
181 + 8641781 = 8641962

Showing the first eight; more decompositions exist.
