Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545142, here are decompositions:

23 + 33545119 = 33545142
31 + 33545111 = 33545142
41 + 33545101 = 33545142
149 + 33544993 = 33545142
193 + 33544949 = 33545142
271 + 33544871 = 33545142
331 + 33544811 = 33545142
359 + 33544783 = 33545142

Showing the first eight; more decompositions exist.
