Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487320, here are decompositions:

7 + 33487313 = 33487320
11 + 33487309 = 33487320
19 + 33487301 = 33487320
43 + 33487277 = 33487320
47 + 33487273 = 33487320
59 + 33487261 = 33487320
73 + 33487247 = 33487320
101 + 33487219 = 33487320

Showing the first eight; more decompositions exist.
