Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668228, here are decompositions:

71 + 8668157 = 8668228
167 + 8668061 = 8668228
197 + 8668031 = 8668228
227 + 8668001 = 8668228
419 + 8667809 = 8668228
431 + 8667797 = 8668228
521 + 8667707 = 8668228
587 + 8667641 = 8668228

Showing the first eight; more decompositions exist.
