Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516378, here are decompositions:

29 + 33516349 = 33516378
37 + 33516341 = 33516378
41 + 33516337 = 33516378
59 + 33516319 = 33516378
61 + 33516317 = 33516378
89 + 33516289 = 33516378
101 + 33516277 = 33516378
109 + 33516269 = 33516378

Showing the first eight; more decompositions exist.
