Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538464, here are decompositions:

7 + 33538457 = 33538464
17 + 33538447 = 33538464
23 + 33538441 = 33538464
61 + 33538403 = 33538464
97 + 33538367 = 33538464
137 + 33538327 = 33538464
151 + 33538313 = 33538464
191 + 33538273 = 33538464

Showing the first eight; more decompositions exist.
