Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33611840, here are decompositions:

19 + 33611821 = 33611840
43 + 33611797 = 33611840
127 + 33611713 = 33611840
139 + 33611701 = 33611840
211 + 33611629 = 33611840
373 + 33611467 = 33611840
433 + 33611407 = 33611840
439 + 33611401 = 33611840

Showing the first eight; more decompositions exist.
