Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611236, here are decompositions:

17 + 8611219 = 8611236
89 + 8611147 = 8611236
97 + 8611139 = 8611236
103 + 8611133 = 8611236
173 + 8611063 = 8611236
199 + 8611037 = 8611236
233 + 8611003 = 8611236
239 + 8610997 = 8611236

Showing the first eight; more decompositions exist.
