Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749086, here are decompositions:

37 + 8749049 = 8749086
67 + 8749019 = 8749086
79 + 8749007 = 8749086
97 + 8748989 = 8749086
107 + 8748979 = 8749086
113 + 8748973 = 8749086
193 + 8748893 = 8749086
197 + 8748889 = 8749086

Showing the first eight; more decompositions exist.
