Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644436, here are decompositions:

109 + 8644327 = 8644436
193 + 8644243 = 8644436
223 + 8644213 = 8644436
313 + 8644123 = 8644436
379 + 8644057 = 8644436
439 + 8643997 = 8644436
547 + 8643889 = 8644436
739 + 8643697 = 8644436

Showing the first eight; more decompositions exist.
