Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182154, here are decompositions:

13 + 182141 = 182154
23 + 182131 = 182154
31 + 182123 = 182154
43 + 182111 = 182154
47 + 182107 = 182154
53 + 182101 = 182154
97 + 182057 = 182154
107 + 182047 = 182154

Showing the first eight; more decompositions exist.
