Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722284, here are decompositions:

47 + 8722237 = 8722284
61 + 8722223 = 8722284
73 + 8722211 = 8722284
97 + 8722187 = 8722284
113 + 8722171 = 8722284
167 + 8722117 = 8722284
191 + 8722093 = 8722284
251 + 8722033 = 8722284

Showing the first eight; more decompositions exist.
