Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164382, here are decompositions:

5 + 164377 = 164382
11 + 164371 = 164382
19 + 164363 = 164382
41 + 164341 = 164382
61 + 164321 = 164382
73 + 164309 = 164382
83 + 164299 = 164382
103 + 164279 = 164382

Showing the first eight; more decompositions exist.
