Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491972, here are decompositions:

13 + 33491959 = 33491972
43 + 33491929 = 33491972
139 + 33491833 = 33491972
193 + 33491779 = 33491972
211 + 33491761 = 33491972
331 + 33491641 = 33491972
373 + 33491599 = 33491972
379 + 33491593 = 33491972

Showing the first eight; more decompositions exist.
