Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553638, here are decompositions:

5 + 33553633 = 33553638
31 + 33553607 = 33553638
61 + 33553577 = 33553638
89 + 33553549 = 33553638
101 + 33553537 = 33553638
127 + 33553511 = 33553638
149 + 33553489 = 33553638
269 + 33553369 = 33553638

Showing the first eight; more decompositions exist.
