Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541780, here are decompositions:

11 + 33541769 = 33541780
23 + 33541757 = 33541780
47 + 33541733 = 33541780
71 + 33541709 = 33541780
113 + 33541667 = 33541780
179 + 33541601 = 33541780
317 + 33541463 = 33541780
347 + 33541433 = 33541780

Showing the first eight; more decompositions exist.
