Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557842, here are decompositions:

5 + 33557837 = 33557842
53 + 33557789 = 33557842
89 + 33557753 = 33557842
113 + 33557729 = 33557842
179 + 33557663 = 33557842
239 + 33557603 = 33557842
281 + 33557561 = 33557842
389 + 33557453 = 33557842

Showing the first eight; more decompositions exist.
