Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555990, here are decompositions:

19 + 33555971 = 33555990
31 + 33555959 = 33555990
43 + 33555947 = 33555990
59 + 33555931 = 33555990
89 + 33555901 = 33555990
107 + 33555883 = 33555990
131 + 33555859 = 33555990
137 + 33555853 = 33555990

Showing the first eight; more decompositions exist.
