Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189872, here are decompositions:

13 + 189859 = 189872
19 + 189853 = 189872
73 + 189799 = 189872
139 + 189733 = 189872
181 + 189691 = 189872
211 + 189661 = 189872
229 + 189643 = 189872
313 + 189559 = 189872

Showing the first eight; more decompositions exist.
