Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621606, here are decompositions:

127 + 8621479 = 8621606
139 + 8621467 = 8621606
163 + 8621443 = 8621606
193 + 8621413 = 8621606
229 + 8621377 = 8621606
307 + 8621299 = 8621606
397 + 8621209 = 8621606
463 + 8621143 = 8621606

Showing the first eight; more decompositions exist.
