Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545990, here are decompositions:

3 + 33545987 = 33545990
31 + 33545959 = 33545990
61 + 33545929 = 33545990
73 + 33545917 = 33545990
139 + 33545851 = 33545990
151 + 33545839 = 33545990
277 + 33545713 = 33545990
367 + 33545623 = 33545990

Showing the first eight; more decompositions exist.
