Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643244, here are decompositions:

47 + 8643197 = 8643244
101 + 8643143 = 8643244
107 + 8643137 = 8643244
167 + 8643077 = 8643244
191 + 8643053 = 8643244
293 + 8642951 = 8643244
317 + 8642927 = 8643244
347 + 8642897 = 8643244

Showing the first eight; more decompositions exist.
