Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491724, here are decompositions:

5 + 33491719 = 33491724
11 + 33491713 = 33491724
31 + 33491693 = 33491724
43 + 33491681 = 33491724
53 + 33491671 = 33491724
83 + 33491641 = 33491724
103 + 33491621 = 33491724
131 + 33491593 = 33491724

Showing the first eight; more decompositions exist.
