Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621250, here are decompositions:

17 + 33621233 = 33621250
101 + 33621149 = 33621250
137 + 33621113 = 33621250
167 + 33621083 = 33621250
251 + 33620999 = 33621250
359 + 33620891 = 33621250
431 + 33620819 = 33621250
461 + 33620789 = 33621250

Showing the first eight; more decompositions exist.
