Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12844, here are decompositions:

3 + 12841 = 12844
23 + 12821 = 12844
53 + 12791 = 12844
101 + 12743 = 12844
131 + 12713 = 12844
173 + 12671 = 12844
191 + 12653 = 12844
197 + 12647 = 12844

Showing the first eight; more decompositions exist.
