Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669620, here are decompositions:

107 + 8669513 = 8669620
131 + 8669489 = 8669620
137 + 8669483 = 8669620
173 + 8669447 = 8669620
227 + 8669393 = 8669620
269 + 8669351 = 8669620
383 + 8669237 = 8669620
431 + 8669189 = 8669620

Showing the first eight; more decompositions exist.
