Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621280, here are decompositions:

29 + 33621251 = 33621280
47 + 33621233 = 33621280
107 + 33621173 = 33621280
131 + 33621149 = 33621280
167 + 33621113 = 33621280
197 + 33621083 = 33621280
233 + 33621047 = 33621280
281 + 33620999 = 33621280

Showing the first eight; more decompositions exist.
