Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101178, here are decompositions:

5 + 101173 = 101178
17 + 101161 = 101178
19 + 101159 = 101178
29 + 101149 = 101178
37 + 101141 = 101178
59 + 101119 = 101178
61 + 101117 = 101178
67 + 101111 = 101178

Showing the first eight; more decompositions exist.
