Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189380, here are decompositions:

3 + 189377 = 189380
19 + 189361 = 189380
31 + 189349 = 189380
43 + 189337 = 189380
73 + 189307 = 189380
109 + 189271 = 189380
127 + 189253 = 189380
151 + 189229 = 189380

Showing the first eight; more decompositions exist.
