Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189394, here are decompositions:

3 + 189391 = 189394
5 + 189389 = 189394
17 + 189377 = 189394
41 + 189353 = 189394
47 + 189347 = 189394
83 + 189311 = 189394
137 + 189257 = 189394
353 + 189041 = 189394

Showing the first eight; more decompositions exist.
