Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621240, here are decompositions:

7 + 33621233 = 33621240
67 + 33621173 = 33621240
71 + 33621169 = 33621240
127 + 33621113 = 33621240
131 + 33621109 = 33621240
157 + 33621083 = 33621240
173 + 33621067 = 33621240
193 + 33621047 = 33621240

Showing the first eight; more decompositions exist.
