Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507390, here are decompositions:

11 + 33507379 = 33507390
13 + 33507377 = 33507390
31 + 33507359 = 33507390
43 + 33507347 = 33507390
71 + 33507319 = 33507390
83 + 33507307 = 33507390
131 + 33507259 = 33507390
167 + 33507223 = 33507390

Showing the first eight; more decompositions exist.
