Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148398, here are decompositions:

11 + 148387 = 148398
17 + 148381 = 148398
31 + 148367 = 148398
37 + 148361 = 148398
59 + 148339 = 148398
67 + 148331 = 148398
97 + 148301 = 148398
149 + 148249 = 148398

Showing the first eight; more decompositions exist.
