Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189088, here are decompositions:

47 + 189041 = 189088
71 + 189017 = 189088
89 + 188999 = 189088
131 + 188957 = 189088
149 + 188939 = 189088
197 + 188891 = 189088
227 + 188861 = 189088
257 + 188831 = 189088

Showing the first eight; more decompositions exist.
