Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668328, here are decompositions:

61 + 8668267 = 8668328
127 + 8668201 = 8668328
271 + 8668057 = 8668328
349 + 8667979 = 8668328
367 + 8667961 = 8668328
379 + 8667949 = 8668328
397 + 8667931 = 8668328
421 + 8667907 = 8668328

Showing the first eight; more decompositions exist.
