Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545190, here are decompositions:

13 + 33545177 = 33545190
17 + 33545173 = 33545190
23 + 33545167 = 33545190
43 + 33545147 = 33545190
71 + 33545119 = 33545190
79 + 33545111 = 33545190
89 + 33545101 = 33545190
163 + 33545027 = 33545190

Showing the first eight; more decompositions exist.
