Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542428, here are decompositions:

89 + 33542339 = 33542428
107 + 33542321 = 33542428
131 + 33542297 = 33542428
167 + 33542261 = 33542428
191 + 33542237 = 33542428
239 + 33542189 = 33542428
281 + 33542147 = 33542428
317 + 33542111 = 33542428

Showing the first eight; more decompositions exist.
