Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491382, here are decompositions:

11 + 33491371 = 33491382
13 + 33491369 = 33491382
19 + 33491363 = 33491382
79 + 33491303 = 33491382
149 + 33491233 = 33491382
179 + 33491203 = 33491382
229 + 33491153 = 33491382
233 + 33491149 = 33491382

Showing the first eight; more decompositions exist.
