Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28546, here are decompositions:

5 + 28541 = 28546
29 + 28517 = 28546
47 + 28499 = 28546
53 + 28493 = 28546
83 + 28463 = 28546
107 + 28439 = 28546
113 + 28433 = 28546
137 + 28409 = 28546

Showing the first eight; more decompositions exist.
