Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667684, here are decompositions:

7 + 8667677 = 8667684
23 + 8667661 = 8667684
31 + 8667653 = 8667684
43 + 8667641 = 8667684
71 + 8667613 = 8667684
73 + 8667611 = 8667684
83 + 8667601 = 8667684
163 + 8667521 = 8667684

Showing the first eight; more decompositions exist.
