Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644154, here are decompositions:

7 + 8644147 = 8644154
31 + 8644123 = 8644154
73 + 8644081 = 8644154
97 + 8644057 = 8644154
157 + 8643997 = 8644154
163 + 8643991 = 8644154
367 + 8643787 = 8644154
397 + 8643757 = 8644154

Showing the first eight; more decompositions exist.
