Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668370, here are decompositions:

3 + 8668367 = 8668370
13 + 8668357 = 8668370
97 + 8668273 = 8668370
103 + 8668267 = 8668370
163 + 8668207 = 8668370
229 + 8668141 = 8668370
307 + 8668063 = 8668370
313 + 8668057 = 8668370

Showing the first eight; more decompositions exist.
