Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488728, here are decompositions:

11 + 33488717 = 33488728
41 + 33488687 = 33488728
47 + 33488681 = 33488728
59 + 33488669 = 33488728
89 + 33488639 = 33488728
101 + 33488627 = 33488728
179 + 33488549 = 33488728
191 + 33488537 = 33488728

Showing the first eight; more decompositions exist.
