Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607720, here are decompositions:

17 + 33607703 = 33607720
23 + 33607697 = 33607720
101 + 33607619 = 33607720
173 + 33607547 = 33607720
191 + 33607529 = 33607720
383 + 33607337 = 33607720
431 + 33607289 = 33607720
449 + 33607271 = 33607720

Showing the first eight; more decompositions exist.
