Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493808, here are decompositions:

31 + 33493777 = 33493808
181 + 33493627 = 33493808
241 + 33493567 = 33493808
421 + 33493387 = 33493808
487 + 33493321 = 33493808
499 + 33493309 = 33493808
727 + 33493081 = 33493808
811 + 33492997 = 33493808

Showing the first eight; more decompositions exist.
