Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555972, here are decompositions:

13 + 33555959 = 33555972
41 + 33555931 = 33555972
59 + 33555913 = 33555972
71 + 33555901 = 33555972
89 + 33555883 = 33555972
113 + 33555859 = 33555972
173 + 33555799 = 33555972
269 + 33555703 = 33555972

Showing the first eight; more decompositions exist.
