Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667778, here are decompositions:

71 + 8667707 = 8667778
89 + 8667689 = 8667778
101 + 8667677 = 8667778
137 + 8667641 = 8667778
167 + 8667611 = 8667778
239 + 8667539 = 8667778
257 + 8667521 = 8667778
281 + 8667497 = 8667778

Showing the first eight; more decompositions exist.
