Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545472, here are decompositions:

13 + 33545459 = 33545472
29 + 33545443 = 33545472
43 + 33545429 = 33545472
71 + 33545401 = 33545472
83 + 33545389 = 33545472
89 + 33545383 = 33545472
101 + 33545371 = 33545472
139 + 33545333 = 33545472

Showing the first eight; more decompositions exist.
