Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2546, here are decompositions:

3 + 2543 = 2546
7 + 2539 = 2546
43 + 2503 = 2546
73 + 2473 = 2546
79 + 2467 = 2546
109 + 2437 = 2546
157 + 2389 = 2546
163 + 2383 = 2546

Showing the first eight; more decompositions exist.
