Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641236, here are decompositions:

5 + 8641231 = 8641236
89 + 8641147 = 8641236
103 + 8641133 = 8641236
139 + 8641097 = 8641236
157 + 8641079 = 8641236
173 + 8641063 = 8641236
229 + 8641007 = 8641236
269 + 8640967 = 8641236

Showing the first eight; more decompositions exist.
