Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189882, here are decompositions:

5 + 189877 = 189882
23 + 189859 = 189882
29 + 189853 = 189882
31 + 189851 = 189882
59 + 189823 = 189882
83 + 189799 = 189882
139 + 189743 = 189882
149 + 189733 = 189882

Showing the first eight; more decompositions exist.
