Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621970, here are decompositions:

47 + 33621923 = 33621970
59 + 33621911 = 33621970
89 + 33621881 = 33621970
113 + 33621857 = 33621970
131 + 33621839 = 33621970
257 + 33621713 = 33621970
359 + 33621611 = 33621970
479 + 33621491 = 33621970

Showing the first eight; more decompositions exist.
