Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643232, here are decompositions:

23 + 8643209 = 8643232
83 + 8643149 = 8643232
89 + 8643143 = 8643232
149 + 8643083 = 8643232
173 + 8643059 = 8643232
179 + 8643053 = 8643232
281 + 8642951 = 8643232
293 + 8642939 = 8643232

Showing the first eight; more decompositions exist.
