Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572418, here are decompositions:

37 + 33572381 = 33572418
41 + 33572377 = 33572418
67 + 33572351 = 33572418
71 + 33572347 = 33572418
79 + 33572339 = 33572418
107 + 33572311 = 33572418
109 + 33572309 = 33572418
167 + 33572251 = 33572418

Showing the first eight; more decompositions exist.
