Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642416, here are decompositions:

113 + 8642303 = 8642416
179 + 8642237 = 8642416
227 + 8642189 = 8642416
257 + 8642159 = 8642416
269 + 8642147 = 8642416
317 + 8642099 = 8642416
353 + 8642063 = 8642416
359 + 8642057 = 8642416

Showing the first eight; more decompositions exist.
