Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11178, here are decompositions:

5 + 11173 = 11178
7 + 11171 = 11178
17 + 11161 = 11178
19 + 11159 = 11178
29 + 11149 = 11178
47 + 11131 = 11178
59 + 11119 = 11178
61 + 11117 = 11178

Showing the first eight; more decompositions exist.
