Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91228, here are decompositions:

29 + 91199 = 91228
89 + 91139 = 91228
101 + 91127 = 91228
107 + 91121 = 91228
131 + 91097 = 91228
149 + 91079 = 91228
239 + 90989 = 91228
251 + 90977 = 91228

Showing the first eight; more decompositions exist.
