Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4198, here are decompositions:

41 + 4157 = 4198
59 + 4139 = 4198
71 + 4127 = 4198
107 + 4091 = 4198
149 + 4049 = 4198
179 + 4019 = 4198
191 + 4007 = 4198
197 + 4001 = 4198

Showing the first eight; more decompositions exist.
