Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644328, here are decompositions:

67 + 8644261 = 8644328
97 + 8644231 = 8644328
157 + 8644171 = 8644328
181 + 8644147 = 8644328
271 + 8644057 = 8644328
331 + 8643997 = 8644328
337 + 8643991 = 8644328
409 + 8643919 = 8644328

Showing the first eight; more decompositions exist.
