Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545578, here are decompositions:

149 + 33545429 = 33545578
197 + 33545381 = 33545578
251 + 33545327 = 33545578
257 + 33545321 = 33545578
389 + 33545189 = 33545578
401 + 33545177 = 33545578
431 + 33545147 = 33545578
467 + 33545111 = 33545578

Showing the first eight; more decompositions exist.
