Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31194, here are decompositions:

5 + 31189 = 31194
11 + 31183 = 31194
13 + 31181 = 31194
17 + 31177 = 31194
41 + 31153 = 31194
43 + 31151 = 31194
47 + 31147 = 31194
71 + 31123 = 31194

Showing the first eight; more decompositions exist.
