Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572638, here are decompositions:

101 + 33572537 = 33572638
149 + 33572489 = 33572638
191 + 33572447 = 33572638
257 + 33572381 = 33572638
401 + 33572237 = 33572638
419 + 33572219 = 33572638
521 + 33572117 = 33572638
557 + 33572081 = 33572638

Showing the first eight; more decompositions exist.
