Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523820, here are decompositions:

61 + 33523759 = 33523820
97 + 33523723 = 33523820
151 + 33523669 = 33523820
157 + 33523663 = 33523820
241 + 33523579 = 33523820
367 + 33523453 = 33523820
373 + 33523447 = 33523820
397 + 33523423 = 33523820

Showing the first eight; more decompositions exist.
