Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668226, here are decompositions:

19 + 8668207 = 8668226
163 + 8668063 = 8668226
277 + 8667949 = 8668226
313 + 8667913 = 8668226
379 + 8667847 = 8668226
397 + 8667829 = 8668226
433 + 8667793 = 8668226
499 + 8667727 = 8668226

Showing the first eight; more decompositions exist.
