Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28126, here are decompositions:

3 + 28123 = 28126
17 + 28109 = 28126
29 + 28097 = 28126
107 + 28019 = 28126
173 + 27953 = 28126
179 + 27947 = 28126
233 + 27893 = 28126
317 + 27809 = 28126

Showing the first eight; more decompositions exist.
