Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555138, here are decompositions:

7 + 33555131 = 33555138
37 + 33555101 = 33555138
59 + 33555079 = 33555138
61 + 33555077 = 33555138
101 + 33555037 = 33555138
167 + 33554971 = 33555138
179 + 33554959 = 33555138
271 + 33554867 = 33555138

Showing the first eight; more decompositions exist.
