Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188396, here are decompositions:

7 + 188389 = 188396
37 + 188359 = 188396
73 + 188323 = 188396
79 + 188317 = 188396
97 + 188299 = 188396
199 + 188197 = 188396
367 + 188029 = 188396
379 + 188017 = 188396

Showing the first eight; more decompositions exist.
