Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621436, here are decompositions:

29 + 33621407 = 33621436
47 + 33621389 = 33621436
53 + 33621383 = 33621436
137 + 33621299 = 33621436
263 + 33621173 = 33621436
353 + 33621083 = 33621436
389 + 33621047 = 33621436
509 + 33620927 = 33621436

Showing the first eight; more decompositions exist.
