Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537620, here are decompositions:

7 + 33537613 = 33537620
31 + 33537589 = 33537620
79 + 33537541 = 33537620
97 + 33537523 = 33537620
211 + 33537409 = 33537620
223 + 33537397 = 33537620
307 + 33537313 = 33537620
421 + 33537199 = 33537620

Showing the first eight; more decompositions exist.
