Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542530, here are decompositions:

41 + 33542489 = 33542530
53 + 33542477 = 33542530
167 + 33542363 = 33542530
191 + 33542339 = 33542530
233 + 33542297 = 33542530
269 + 33542261 = 33542530
293 + 33542237 = 33542530
311 + 33542219 = 33542530

Showing the first eight; more decompositions exist.
