Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541640, here are decompositions:

19 + 33541621 = 33541640
31 + 33541609 = 33541640
61 + 33541579 = 33541640
103 + 33541537 = 33541640
127 + 33541513 = 33541640
151 + 33541489 = 33541640
157 + 33541483 = 33541640
163 + 33541477 = 33541640

Showing the first eight; more decompositions exist.
