Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189426, here are decompositions:

5 + 189421 = 189426
19 + 189407 = 189426
37 + 189389 = 189426
73 + 189353 = 189426
79 + 189347 = 189426
89 + 189337 = 189426
173 + 189253 = 189426
197 + 189229 = 189426

Showing the first eight; more decompositions exist.
