Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557542, here are decompositions:

71 + 33557471 = 33557542
89 + 33557453 = 33557542
113 + 33557429 = 33557542
131 + 33557411 = 33557542
479 + 33557063 = 33557542
653 + 33556889 = 33557542
701 + 33556841 = 33557542
719 + 33556823 = 33557542

Showing the first eight; more decompositions exist.
