Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189874, here are decompositions:

23 + 189851 = 189874
107 + 189767 = 189874
131 + 189743 = 189874
173 + 189701 = 189874
257 + 189617 = 189874
281 + 189593 = 189874
383 + 189491 = 189874
401 + 189473 = 189874

Showing the first eight; more decompositions exist.
