Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3538, here are decompositions:

5 + 3533 = 3538
11 + 3527 = 3538
47 + 3491 = 3538
71 + 3467 = 3538
89 + 3449 = 3538
131 + 3407 = 3538
149 + 3389 = 3538
167 + 3371 = 3538

Showing the first eight; more decompositions exist.
