Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669586, here are decompositions:

43 + 8669543 = 8669586
59 + 8669527 = 8669586
73 + 8669513 = 8669586
97 + 8669489 = 8669586
103 + 8669483 = 8669586
109 + 8669477 = 8669586
139 + 8669447 = 8669586
193 + 8669393 = 8669586

Showing the first eight; more decompositions exist.
