Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182530, here are decompositions:

11 + 182519 = 182530
41 + 182489 = 182530
59 + 182471 = 182530
107 + 182423 = 182530
113 + 182417 = 182530
191 + 182339 = 182530
197 + 182333 = 182530
233 + 182297 = 182530

Showing the first eight; more decompositions exist.
