Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189478, here are decompositions:

5 + 189473 = 189478
11 + 189467 = 189478
41 + 189437 = 189478
71 + 189407 = 189478
89 + 189389 = 189478
101 + 189377 = 189478
131 + 189347 = 189478
167 + 189311 = 189478

Showing the first eight; more decompositions exist.
