Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115398, here are decompositions:

37 + 115361 = 115398
61 + 115337 = 115398
67 + 115331 = 115398
71 + 115327 = 115398
79 + 115319 = 115398
89 + 115309 = 115398
97 + 115301 = 115398
139 + 115259 = 115398

Showing the first eight; more decompositions exist.
