Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542872, here are decompositions:

5 + 33542867 = 33542872
71 + 33542801 = 33542872
89 + 33542783 = 33542872
113 + 33542759 = 33542872
149 + 33542723 = 33542872
269 + 33542603 = 33542872
383 + 33542489 = 33542872
509 + 33542363 = 33542872

Showing the first eight; more decompositions exist.
