Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547904, here are decompositions:

31 + 33547873 = 33547904
43 + 33547861 = 33547904
73 + 33547831 = 33547904
277 + 33547627 = 33547904
367 + 33547537 = 33547904
457 + 33547447 = 33547904
487 + 33547417 = 33547904
613 + 33547291 = 33547904

Showing the first eight; more decompositions exist.
