Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644424, here are decompositions:

97 + 8644327 = 8644424
163 + 8644261 = 8644424
181 + 8644243 = 8644424
193 + 8644231 = 8644424
211 + 8644213 = 8644424
277 + 8644147 = 8644424
367 + 8644057 = 8644424
433 + 8643991 = 8644424

Showing the first eight; more decompositions exist.
