Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557430, here are decompositions:

7 + 33557423 = 33557430
13 + 33557417 = 33557430
17 + 33557413 = 33557430
19 + 33557411 = 33557430
31 + 33557399 = 33557430
43 + 33557387 = 33557430
73 + 33557357 = 33557430
89 + 33557341 = 33557430

Showing the first eight; more decompositions exist.
