Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537638, here are decompositions:

67 + 33537571 = 33537638
97 + 33537541 = 33537638
109 + 33537529 = 33537638
229 + 33537409 = 33537638
241 + 33537397 = 33537638
439 + 33537199 = 33537638
577 + 33537061 = 33537638
751 + 33536887 = 33537638

Showing the first eight; more decompositions exist.
