Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3546, here are decompositions:

5 + 3541 = 3546
7 + 3539 = 3546
13 + 3533 = 3546
17 + 3529 = 3546
19 + 3527 = 3546
29 + 3517 = 3546
47 + 3499 = 3546
79 + 3467 = 3546

Showing the first eight; more decompositions exist.
