Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39378, here are decompositions:

5 + 39373 = 39378
7 + 39371 = 39378
11 + 39367 = 39378
19 + 39359 = 39378
37 + 39341 = 39378
61 + 39317 = 39378
127 + 39251 = 39378
137 + 39241 = 39378

Showing the first eight; more decompositions exist.
