Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133290, here are decompositions:

7 + 133283 = 133290
11 + 133279 = 133290
13 + 133277 = 133290
19 + 133271 = 133290
29 + 133261 = 133290
37 + 133253 = 133290
89 + 133201 = 133290
103 + 133187 = 133290

Showing the first eight; more decompositions exist.
