Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621418, here are decompositions:

11 + 33621407 = 33621418
29 + 33621389 = 33621418
107 + 33621311 = 33621418
167 + 33621251 = 33621418
269 + 33621149 = 33621418
419 + 33620999 = 33621418
491 + 33620927 = 33621418
599 + 33620819 = 33621418

Showing the first eight; more decompositions exist.
