Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667860, here are decompositions:

13 + 8667847 = 8667860
31 + 8667829 = 8667860
67 + 8667793 = 8667860
127 + 8667733 = 8667860
139 + 8667721 = 8667860
163 + 8667697 = 8667860
199 + 8667661 = 8667860
349 + 8667511 = 8667860

Showing the first eight; more decompositions exist.
