Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572740, here are decompositions:

41 + 33572699 = 33572740
53 + 33572687 = 33572740
251 + 33572489 = 33572740
293 + 33572447 = 33572740
359 + 33572381 = 33572740
389 + 33572351 = 33572740
401 + 33572339 = 33572740
431 + 33572309 = 33572740

Showing the first eight; more decompositions exist.
