Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507520, here are decompositions:

17 + 33507503 = 33507520
107 + 33507413 = 33507520
113 + 33507407 = 33507520
173 + 33507347 = 33507520
353 + 33507167 = 33507520
383 + 33507137 = 33507520
461 + 33507059 = 33507520
491 + 33507029 = 33507520

Showing the first eight; more decompositions exist.
