Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487628, here are decompositions:

7 + 33487621 = 33487628
37 + 33487591 = 33487628
67 + 33487561 = 33487628
151 + 33487477 = 33487628
211 + 33487417 = 33487628
241 + 33487387 = 33487628
367 + 33487261 = 33487628
409 + 33487219 = 33487628

Showing the first eight; more decompositions exist.
