Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621378, here are decompositions:

17 + 33621361 = 33621378
67 + 33621311 = 33621378
79 + 33621299 = 33621378
127 + 33621251 = 33621378
229 + 33621149 = 33621378
269 + 33621109 = 33621378
311 + 33621067 = 33621378
331 + 33621047 = 33621378

Showing the first eight; more decompositions exist.
