Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642248, here are decompositions:

11 + 8642237 = 8642248
59 + 8642189 = 8642248
89 + 8642159 = 8642248
101 + 8642147 = 8642248
107 + 8642141 = 8642248
137 + 8642111 = 8642248
149 + 8642099 = 8642248
191 + 8642057 = 8642248

Showing the first eight; more decompositions exist.
