Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164394, here are decompositions:

7 + 164387 = 164394
17 + 164377 = 164394
23 + 164371 = 164394
31 + 164363 = 164394
37 + 164357 = 164394
53 + 164341 = 164394
73 + 164321 = 164394
103 + 164291 = 164394

Showing the first eight; more decompositions exist.
