Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12826, here are decompositions:

3 + 12823 = 12826
5 + 12821 = 12826
17 + 12809 = 12826
83 + 12743 = 12826
113 + 12713 = 12826
137 + 12689 = 12826
167 + 12659 = 12826
173 + 12653 = 12826

Showing the first eight; more decompositions exist.
