Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189506, here are decompositions:

13 + 189493 = 189506
43 + 189463 = 189506
67 + 189439 = 189506
73 + 189433 = 189506
157 + 189349 = 189506
199 + 189307 = 189506
277 + 189229 = 189506
283 + 189223 = 189506

Showing the first eight; more decompositions exist.
