Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668342, here are decompositions:

41 + 8668301 = 8668342
149 + 8668193 = 8668342
191 + 8668151 = 8668342
269 + 8668073 = 8668342
281 + 8668061 = 8668342
311 + 8668031 = 8668342
443 + 8667899 = 8668342
479 + 8667863 = 8668342

Showing the first eight; more decompositions exist.
