Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187164, here are decompositions:

23 + 187141 = 187164
31 + 187133 = 187164
37 + 187127 = 187164
41 + 187123 = 187164
53 + 187111 = 187164
73 + 187091 = 187164
83 + 187081 = 187164
97 + 187067 = 187164

Showing the first eight; more decompositions exist.
