Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669776, here are decompositions:

107 + 8669669 = 8669776
149 + 8669627 = 8669776
233 + 8669543 = 8669776
263 + 8669513 = 8669776
293 + 8669483 = 8669776
359 + 8669417 = 8669776
383 + 8669393 = 8669776
443 + 8669333 = 8669776

Showing the first eight; more decompositions exist.
