Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742086, here are decompositions:

19 + 8742067 = 8742086
97 + 8741989 = 8742086
103 + 8741983 = 8742086
109 + 8741977 = 8742086
139 + 8741947 = 8742086
163 + 8741923 = 8742086
307 + 8741779 = 8742086
337 + 8741749 = 8742086

Showing the first eight; more decompositions exist.
