Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505418, here are decompositions:

109 + 33505309 = 33505418
157 + 33505261 = 33505418
241 + 33505177 = 33505418
367 + 33505051 = 33505418
379 + 33505039 = 33505418
409 + 33505009 = 33505418
601 + 33504817 = 33505418
631 + 33504787 = 33505418

Showing the first eight; more decompositions exist.
