Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009228, here are decompositions:

29 + 1009199 = 1009228
71 + 1009157 = 1009228
89 + 1009139 = 1009228
107 + 1009121 = 1009228
131 + 1009097 = 1009228
167 + 1009061 = 1009228
179 + 1009049 = 1009228
191 + 1009037 = 1009228

Showing the first eight; more decompositions exist.
