Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625578, here are decompositions:

11 + 33625567 = 33625578
17 + 33625561 = 33625578
31 + 33625547 = 33625578
67 + 33625511 = 33625578
101 + 33625477 = 33625578
127 + 33625451 = 33625578
131 + 33625447 = 33625578
149 + 33625429 = 33625578

Showing the first eight; more decompositions exist.
