Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669564, here are decompositions:

37 + 8669527 = 8669564
223 + 8669341 = 8669564
271 + 8669293 = 8669564
313 + 8669251 = 8669564
331 + 8669233 = 8669564
457 + 8669107 = 8669564
523 + 8669041 = 8669564
571 + 8668993 = 8669564

Showing the first eight; more decompositions exist.
