Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12798, here are decompositions:

7 + 12791 = 12798
17 + 12781 = 12798
41 + 12757 = 12798
59 + 12739 = 12798
101 + 12697 = 12798
109 + 12689 = 12798
127 + 12671 = 12798
139 + 12659 = 12798

Showing the first eight; more decompositions exist.
