Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542138, here are decompositions:

37 + 33542101 = 33542138
61 + 33542077 = 33542138
151 + 33541987 = 33542138
181 + 33541957 = 33542138
199 + 33541939 = 33542138
229 + 33541909 = 33542138
277 + 33541861 = 33542138
337 + 33541801 = 33542138

Showing the first eight; more decompositions exist.
