Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538880, here are decompositions:

7 + 33538873 = 33538880
13 + 33538867 = 33538880
79 + 33538801 = 33538880
97 + 33538783 = 33538880
139 + 33538741 = 33538880
181 + 33538699 = 33538880
241 + 33538639 = 33538880
337 + 33538543 = 33538880

Showing the first eight; more decompositions exist.
