Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7798, here are decompositions:

5 + 7793 = 7798
41 + 7757 = 7798
71 + 7727 = 7798
107 + 7691 = 7798
149 + 7649 = 7798
191 + 7607 = 7798
239 + 7559 = 7798
251 + 7547 = 7798

Showing the first eight; more decompositions exist.
