Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6546, here are decompositions:

17 + 6529 = 6546
73 + 6473 = 6546
97 + 6449 = 6546
149 + 6397 = 6546
157 + 6389 = 6546
167 + 6379 = 6546
173 + 6373 = 6546
179 + 6367 = 6546

Showing the first eight; more decompositions exist.
