Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507450, here are decompositions:

7 + 33507443 = 33507450
37 + 33507413 = 33507450
43 + 33507407 = 33507450
71 + 33507379 = 33507450
73 + 33507377 = 33507450
103 + 33507347 = 33507450
131 + 33507319 = 33507450
191 + 33507259 = 33507450

Showing the first eight; more decompositions exist.
