Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642236, here are decompositions:

47 + 8642189 = 8642236
89 + 8642147 = 8642236
137 + 8642099 = 8642236
173 + 8642063 = 8642236
179 + 8642057 = 8642236
233 + 8642003 = 8642236
353 + 8641883 = 8642236
419 + 8641817 = 8642236

Showing the first eight; more decompositions exist.
