Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667988, here are decompositions:

59 + 8667929 = 8667988
89 + 8667899 = 8667988
167 + 8667821 = 8667988
179 + 8667809 = 8667988
191 + 8667797 = 8667988
281 + 8667707 = 8667988
311 + 8667677 = 8667988
347 + 8667641 = 8667988

Showing the first eight; more decompositions exist.
