Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491478, here are decompositions:

11 + 33491467 = 33491478
17 + 33491461 = 33491478
19 + 33491459 = 33491478
37 + 33491441 = 33491478
61 + 33491417 = 33491478
107 + 33491371 = 33491478
109 + 33491369 = 33491478
211 + 33491267 = 33491478

Showing the first eight; more decompositions exist.
