Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189742, here are decompositions:

29 + 189713 = 189742
41 + 189701 = 189742
71 + 189671 = 189742
89 + 189653 = 189742
149 + 189593 = 189742
233 + 189509 = 189742
251 + 189491 = 189742
263 + 189479 = 189742

Showing the first eight; more decompositions exist.
