Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33558728, here are decompositions:

37 + 33558691 = 33558728
79 + 33558649 = 33558728
139 + 33558589 = 33558728
271 + 33558457 = 33558728
277 + 33558451 = 33558728
457 + 33558271 = 33558728
661 + 33558067 = 33558728
787 + 33557941 = 33558728

Showing the first eight; more decompositions exist.
