Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103198, here are decompositions:

107 + 103091 = 103198
131 + 103067 = 103198
149 + 103049 = 103198
191 + 103007 = 103198
197 + 103001 = 103198
269 + 102929 = 103198
317 + 102881 = 103198
401 + 102797 = 103198

Showing the first eight; more decompositions exist.
