Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189450, here are decompositions:

11 + 189439 = 189450
13 + 189437 = 189450
17 + 189433 = 189450
29 + 189421 = 189450
43 + 189407 = 189450
59 + 189391 = 189450
61 + 189389 = 189450
73 + 189377 = 189450

Showing the first eight; more decompositions exist.
