Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561630, here are decompositions:

19 + 33561611 = 33561630
23 + 33561607 = 33561630
31 + 33561599 = 33561630
59 + 33561571 = 33561630
71 + 33561559 = 33561630
73 + 33561557 = 33561630
79 + 33561551 = 33561630
97 + 33561533 = 33561630

Showing the first eight; more decompositions exist.
