Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537218, here are decompositions:

19 + 33537199 = 33537218
31 + 33537187 = 33537218
97 + 33537121 = 33537218
157 + 33537061 = 33537218
277 + 33536941 = 33537218
331 + 33536887 = 33537218
367 + 33536851 = 33537218
409 + 33536809 = 33537218

Showing the first eight; more decompositions exist.
