Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186396, here are decompositions:

5 + 186391 = 186396
17 + 186379 = 186396
19 + 186377 = 186396
53 + 186343 = 186396
79 + 186317 = 186396
97 + 186299 = 186396
113 + 186283 = 186396
137 + 186259 = 186396

Showing the first eight; more decompositions exist.
