Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161394, here are decompositions:

7 + 161387 = 161394
17 + 161377 = 161394
31 + 161363 = 161394
53 + 161341 = 161394
61 + 161333 = 161394
71 + 161323 = 161394
113 + 161281 = 161394
127 + 161267 = 161394

Showing the first eight; more decompositions exist.
