Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481538, here are decompositions:

31 + 33481507 = 33481538
67 + 33481471 = 33481538
109 + 33481429 = 33481538
199 + 33481339 = 33481538
229 + 33481309 = 33481538
379 + 33481159 = 33481538
421 + 33481117 = 33481538
439 + 33481099 = 33481538

Showing the first eight; more decompositions exist.
