Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555420, here are decompositions:

23 + 33555397 = 33555420
29 + 33555391 = 33555420
37 + 33555383 = 33555420
43 + 33555377 = 33555420
47 + 33555373 = 33555420
79 + 33555341 = 33555420
103 + 33555317 = 33555420
127 + 33555293 = 33555420

Showing the first eight; more decompositions exist.
