Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537428, here are decompositions:

19 + 33537409 = 33537428
31 + 33537397 = 33537428
229 + 33537199 = 33537428
241 + 33537187 = 33537428
307 + 33537121 = 33537428
367 + 33537061 = 33537428
487 + 33536941 = 33537428
541 + 33536887 = 33537428

Showing the first eight; more decompositions exist.
