Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493928, here are decompositions:

7 + 33493921 = 33493928
37 + 33493891 = 33493928
151 + 33493777 = 33493928
211 + 33493717 = 33493928
337 + 33493591 = 33493928
379 + 33493549 = 33493928
541 + 33493387 = 33493928
607 + 33493321 = 33493928

Showing the first eight; more decompositions exist.
