Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491538, here are decompositions:

5 + 33491533 = 33491538
71 + 33491467 = 33491538
79 + 33491459 = 33491538
97 + 33491441 = 33491538
151 + 33491387 = 33491538
167 + 33491371 = 33491538
271 + 33491267 = 33491538
277 + 33491261 = 33491538

Showing the first eight; more decompositions exist.
