Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547440, here are decompositions:

7 + 33547433 = 33547440
19 + 33547421 = 33547440
23 + 33547417 = 33547440
53 + 33547387 = 33547440
67 + 33547373 = 33547440
103 + 33547337 = 33547440
127 + 33547313 = 33547440
131 + 33547309 = 33547440

Showing the first eight; more decompositions exist.
