Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647236, here are decompositions:

5 + 8647231 = 8647236
7 + 8647229 = 8647236
43 + 8647193 = 8647236
53 + 8647183 = 8647236
79 + 8647157 = 8647236
97 + 8647139 = 8647236
107 + 8647129 = 8647236
109 + 8647127 = 8647236

Showing the first eight; more decompositions exist.
