Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644162, here are decompositions:

5 + 8644157 = 8644162
71 + 8644091 = 8644162
101 + 8644061 = 8644162
113 + 8644049 = 8644162
239 + 8643923 = 8644162
269 + 8643893 = 8644162
311 + 8643851 = 8644162
383 + 8643779 = 8644162

Showing the first eight; more decompositions exist.
