Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189902, here are decompositions:

43 + 189859 = 189902
79 + 189823 = 189902
103 + 189799 = 189902
211 + 189691 = 189902
241 + 189661 = 189902
283 + 189619 = 189902
373 + 189529 = 189902
379 + 189523 = 189902

Showing the first eight; more decompositions exist.
