Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491736, here are decompositions:

7 + 33491729 = 33491736
17 + 33491719 = 33491736
23 + 33491713 = 33491736
43 + 33491693 = 33491736
97 + 33491639 = 33491736
137 + 33491599 = 33491736
167 + 33491569 = 33491736
193 + 33491543 = 33491736

Showing the first eight; more decompositions exist.
