Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644248, here are decompositions:

5 + 8644243 = 8644248
17 + 8644231 = 8644248
61 + 8644187 = 8644248
101 + 8644147 = 8644248
157 + 8644091 = 8644248
167 + 8644081 = 8644248
191 + 8644057 = 8644248
199 + 8644049 = 8644248

Showing the first eight; more decompositions exist.
