Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531408, here are decompositions:

5 + 33531403 = 33531408
11 + 33531397 = 33531408
17 + 33531391 = 33531408
19 + 33531389 = 33531408
59 + 33531349 = 33531408
61 + 33531347 = 33531408
89 + 33531319 = 33531408
109 + 33531299 = 33531408

Showing the first eight; more decompositions exist.
