Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545890, here are decompositions:

71 + 33545819 = 33545890
101 + 33545789 = 33545890
107 + 33545783 = 33545890
167 + 33545723 = 33545890
197 + 33545693 = 33545890
233 + 33545657 = 33545890
239 + 33545651 = 33545890
281 + 33545609 = 33545890

Showing the first eight; more decompositions exist.
