Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538448, here are decompositions:

7 + 33538441 = 33538448
61 + 33538387 = 33538448
109 + 33538339 = 33538448
127 + 33538321 = 33538448
241 + 33538207 = 33538448
367 + 33538081 = 33538448
379 + 33538069 = 33538448
397 + 33538051 = 33538448

Showing the first eight; more decompositions exist.
