Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669542, here are decompositions:

29 + 8669513 = 8669542
41 + 8669501 = 8669542
53 + 8669489 = 8669542
59 + 8669483 = 8669542
131 + 8669411 = 8669542
149 + 8669393 = 8669542
191 + 8669351 = 8669542
263 + 8669279 = 8669542

Showing the first eight; more decompositions exist.
