Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158394, here are decompositions:

23 + 158371 = 158394
31 + 158363 = 158394
37 + 158357 = 158394
43 + 158351 = 158394
53 + 158341 = 158394
101 + 158293 = 158394
151 + 158243 = 158394
163 + 158231 = 158394

Showing the first eight; more decompositions exist.
