Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677890, here are decompositions:

7 + 8677883 = 8677890
43 + 8677847 = 8677890
61 + 8677829 = 8677890
127 + 8677763 = 8677890
131 + 8677759 = 8677890
163 + 8677727 = 8677890
167 + 8677723 = 8677890
227 + 8677663 = 8677890

Showing the first eight; more decompositions exist.
