Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507618, here are decompositions:

7 + 33507611 = 33507618
17 + 33507601 = 33507618
19 + 33507599 = 33507618
41 + 33507577 = 33507618
211 + 33507407 = 33507618
239 + 33507379 = 33507618
241 + 33507377 = 33507618
271 + 33507347 = 33507618

Showing the first eight; more decompositions exist.
