Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644236, here are decompositions:

5 + 8644231 = 8644236
23 + 8644213 = 8644236
79 + 8644157 = 8644236
89 + 8644147 = 8644236
113 + 8644123 = 8644236
179 + 8644057 = 8644236
239 + 8643997 = 8644236
277 + 8643959 = 8644236

Showing the first eight; more decompositions exist.
