Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618236, here are decompositions:

23 + 8618213 = 8618236
89 + 8618147 = 8618236
149 + 8618087 = 8618236
173 + 8618063 = 8618236
293 + 8617943 = 8618236
359 + 8617877 = 8618236
449 + 8617787 = 8618236
467 + 8617769 = 8618236

Showing the first eight; more decompositions exist.
