Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542620, here are decompositions:

3 + 33542617 = 33542620
17 + 33542603 = 33542620
47 + 33542573 = 33542620
53 + 33542567 = 33542620
131 + 33542489 = 33542620
257 + 33542363 = 33542620
281 + 33542339 = 33542620
359 + 33542261 = 33542620

Showing the first eight; more decompositions exist.
