Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572218, here are decompositions:

101 + 33572117 = 33572218
137 + 33572081 = 33572218
167 + 33572051 = 33572218
191 + 33572027 = 33572218
389 + 33571829 = 33572218
401 + 33571817 = 33572218
479 + 33571739 = 33572218
509 + 33571709 = 33572218

Showing the first eight; more decompositions exist.
