Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620666, here are decompositions:

7 + 33620659 = 33620666
43 + 33620623 = 33620666
73 + 33620593 = 33620666
103 + 33620563 = 33620666
139 + 33620527 = 33620666
193 + 33620473 = 33620666
199 + 33620467 = 33620666
229 + 33620437 = 33620666

Showing the first eight; more decompositions exist.
