Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553620, here are decompositions:

7 + 33553613 = 33553620
13 + 33553607 = 33553620
43 + 33553577 = 33553620
71 + 33553549 = 33553620
73 + 33553547 = 33553620
83 + 33553537 = 33553620
101 + 33553519 = 33553620
103 + 33553517 = 33553620

Showing the first eight; more decompositions exist.
