Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557418, here are decompositions:

5 + 33557413 = 33557418
7 + 33557411 = 33557418
19 + 33557399 = 33557418
31 + 33557387 = 33557418
61 + 33557357 = 33557418
79 + 33557339 = 33557418
101 + 33557317 = 33557418
317 + 33557101 = 33557418

Showing the first eight; more decompositions exist.
