Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621910, here are decompositions:

29 + 33621881 = 33621910
53 + 33621857 = 33621910
71 + 33621839 = 33621910
149 + 33621761 = 33621910
197 + 33621713 = 33621910
281 + 33621629 = 33621910
317 + 33621593 = 33621910
419 + 33621491 = 33621910

Showing the first eight; more decompositions exist.
