Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538446, here are decompositions:

5 + 33538441 = 33538446
43 + 33538403 = 33538446
59 + 33538387 = 33538446
79 + 33538367 = 33538446
103 + 33538343 = 33538446
107 + 33538339 = 33538446
173 + 33538273 = 33538446
199 + 33538247 = 33538446

Showing the first eight; more decompositions exist.
