Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499720, here are decompositions:

17 + 33499703 = 33499720
29 + 33499691 = 33499720
71 + 33499649 = 33499720
83 + 33499637 = 33499720
101 + 33499619 = 33499720
311 + 33499409 = 33499720
347 + 33499373 = 33499720
389 + 33499331 = 33499720

Showing the first eight; more decompositions exist.
