Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617628, here are decompositions:

67 + 8617561 = 8617628
79 + 8617549 = 8617628
109 + 8617519 = 8617628
181 + 8617447 = 8617628
211 + 8617417 = 8617628
337 + 8617291 = 8617628
367 + 8617261 = 8617628
421 + 8617207 = 8617628

Showing the first eight; more decompositions exist.
