Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182528, here are decompositions:

19 + 182509 = 182528
61 + 182467 = 182528
97 + 182431 = 182528
139 + 182389 = 182528
349 + 182179 = 182528
397 + 182131 = 182528
421 + 182107 = 182528
439 + 182089 = 182528

Showing the first eight; more decompositions exist.
