Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572842, here are decompositions:

29 + 33572813 = 33572842
101 + 33572741 = 33572842
353 + 33572489 = 33572842
461 + 33572381 = 33572842
491 + 33572351 = 33572842
503 + 33572339 = 33572842
509 + 33572333 = 33572842
701 + 33572141 = 33572842

Showing the first eight; more decompositions exist.
