Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667890, here are decompositions:

19 + 8667871 = 8667890
43 + 8667847 = 8667890
61 + 8667829 = 8667890
97 + 8667793 = 8667890
157 + 8667733 = 8667890
163 + 8667727 = 8667890
193 + 8667697 = 8667890
229 + 8667661 = 8667890

Showing the first eight; more decompositions exist.
