Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668244, here are decompositions:

37 + 8668207 = 8668244
43 + 8668201 = 8668244
103 + 8668141 = 8668244
163 + 8668081 = 8668244
181 + 8668063 = 8668244
271 + 8667973 = 8668244
283 + 8667961 = 8668244
313 + 8667931 = 8668244

Showing the first eight; more decompositions exist.
