Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612666, here are decompositions:

3 + 8612663 = 8612666
37 + 8612629 = 8612666
163 + 8612503 = 8612666
193 + 8612473 = 8612666
229 + 8612437 = 8612666
367 + 8612299 = 8612666
373 + 8612293 = 8612666
457 + 8612209 = 8612666

Showing the first eight; more decompositions exist.
