Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538518, here are decompositions:

7 + 33538511 = 33538518
11 + 33538507 = 33538518
19 + 33538499 = 33538518
37 + 33538481 = 33538518
61 + 33538457 = 33538518
71 + 33538447 = 33538518
131 + 33538387 = 33538518
151 + 33538367 = 33538518

Showing the first eight; more decompositions exist.
