Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621860, here are decompositions:

3 + 33621857 = 33621860
37 + 33621823 = 33621860
73 + 33621787 = 33621860
79 + 33621781 = 33621860
109 + 33621751 = 33621860
199 + 33621661 = 33621860
211 + 33621649 = 33621860
463 + 33621397 = 33621860

Showing the first eight; more decompositions exist.
