Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20392, here are decompositions:

3 + 20389 = 20392
23 + 20369 = 20392
59 + 20333 = 20392
131 + 20261 = 20392
173 + 20219 = 20392
191 + 20201 = 20392
263 + 20129 = 20392
269 + 20123 = 20392

Showing the first eight; more decompositions exist.
