Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673990, here are decompositions:

37 + 8673953 = 8673990
67 + 8673923 = 8673990
79 + 8673911 = 8673990
89 + 8673901 = 8673990
113 + 8673877 = 8673990
151 + 8673839 = 8673990
173 + 8673817 = 8673990
229 + 8673761 = 8673990

Showing the first eight; more decompositions exist.
