Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673858, here are decompositions:

19 + 8673839 = 8673858
41 + 8673817 = 8673858
97 + 8673761 = 8673858
131 + 8673727 = 8673858
181 + 8673677 = 8673858
257 + 8673601 = 8673858
311 + 8673547 = 8673858
359 + 8673499 = 8673858

Showing the first eight; more decompositions exist.
