Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42794, here are decompositions:

7 + 42787 = 42794
43 + 42751 = 42794
67 + 42727 = 42794
97 + 42697 = 42794
127 + 42667 = 42794
151 + 42643 = 42794
223 + 42571 = 42794
307 + 42487 = 42794

Showing the first eight; more decompositions exist.
