Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644132, here are decompositions:

41 + 8644091 = 8644132
71 + 8644061 = 8644132
83 + 8644049 = 8644132
113 + 8644019 = 8644132
173 + 8643959 = 8644132
179 + 8643953 = 8644132
191 + 8643941 = 8644132
239 + 8643893 = 8644132

Showing the first eight; more decompositions exist.
