Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669242, here are decompositions:

3 + 8669239 = 8669242
5 + 8669237 = 8669242
53 + 8669189 = 8669242
83 + 8669159 = 8669242
269 + 8668973 = 8669242
353 + 8668889 = 8669242
443 + 8668799 = 8669242
479 + 8668763 = 8669242

Showing the first eight; more decompositions exist.
