Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188798, here are decompositions:

7 + 188791 = 188798
19 + 188779 = 188798
31 + 188767 = 188798
79 + 188719 = 188798
97 + 188701 = 188798
271 + 188527 = 188798
307 + 188491 = 188798
367 + 188431 = 188798

Showing the first eight; more decompositions exist.
