Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105398, here are decompositions:

19 + 105379 = 105398
31 + 105367 = 105398
37 + 105361 = 105398
61 + 105337 = 105398
67 + 105331 = 105398
79 + 105319 = 105398
199 + 105199 = 105398
367 + 105031 = 105398

Showing the first eight; more decompositions exist.
