Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33541440, here are decompositions:

7 + 33541433 = 33541440
13 + 33541427 = 33541440
109 + 33541331 = 33541440
131 + 33541309 = 33541440
137 + 33541303 = 33541440
139 + 33541301 = 33541440
181 + 33541259 = 33541440
223 + 33541217 = 33541440

Showing the first eight; more decompositions exist.
