Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542372, here are decompositions:

13 + 33542359 = 33542372
109 + 33542263 = 33542372
139 + 33542233 = 33542372
181 + 33542191 = 33542372
271 + 33542101 = 33542372
349 + 33542023 = 33542372
433 + 33541939 = 33542372
439 + 33541933 = 33542372

Showing the first eight; more decompositions exist.
