Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669572, here are decompositions:

29 + 8669543 = 8669572
59 + 8669513 = 8669572
71 + 8669501 = 8669572
83 + 8669489 = 8669572
89 + 8669483 = 8669572
173 + 8669399 = 8669572
179 + 8669393 = 8669572
239 + 8669333 = 8669572

Showing the first eight; more decompositions exist.
