Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491768, here are decompositions:

7 + 33491761 = 33491768
97 + 33491671 = 33491768
127 + 33491641 = 33491768
199 + 33491569 = 33491768
307 + 33491461 = 33491768
397 + 33491371 = 33491768
547 + 33491221 = 33491768
619 + 33491149 = 33491768

Showing the first eight; more decompositions exist.
