Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189530, here are decompositions:

7 + 189523 = 189530
13 + 189517 = 189530
37 + 189493 = 189530
67 + 189463 = 189530
97 + 189433 = 189530
109 + 189421 = 189530
139 + 189391 = 189530
181 + 189349 = 189530

Showing the first eight; more decompositions exist.
