Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189788, here are decompositions:

31 + 189757 = 189788
97 + 189691 = 189788
127 + 189661 = 189788
229 + 189559 = 189788
241 + 189547 = 189788
271 + 189517 = 189788
349 + 189439 = 189788
367 + 189421 = 189788

Showing the first eight; more decompositions exist.
