Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493788, here are decompositions:

5 + 33493783 = 33493788
11 + 33493777 = 33493788
71 + 33493717 = 33493788
149 + 33493639 = 33493788
197 + 33493591 = 33493788
239 + 33493549 = 33493788
397 + 33493391 = 33493788
401 + 33493387 = 33493788

Showing the first eight; more decompositions exist.
