Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541638, here are decompositions:

17 + 33541621 = 33541638
19 + 33541619 = 33541638
29 + 33541609 = 33541638
37 + 33541601 = 33541638
59 + 33541579 = 33541638
61 + 33541577 = 33541638
101 + 33541537 = 33541638
131 + 33541507 = 33541638

Showing the first eight; more decompositions exist.
