Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182340, here are decompositions:

7 + 182333 = 182340
31 + 182309 = 182340
43 + 182297 = 182340
61 + 182279 = 182340
79 + 182261 = 182340
97 + 182243 = 182340
101 + 182239 = 182340
107 + 182233 = 182340

Showing the first eight; more decompositions exist.
