Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491556, here are decompositions:

13 + 33491543 = 33491556
19 + 33491537 = 33491556
23 + 33491533 = 33491556
67 + 33491489 = 33491556
89 + 33491467 = 33491556
97 + 33491459 = 33491556
139 + 33491417 = 33491556
193 + 33491363 = 33491556

Showing the first eight; more decompositions exist.
