Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747086, here are decompositions:

3 + 8747083 = 8747086
107 + 8746979 = 8747086
137 + 8746949 = 8747086
149 + 8746937 = 8747086
167 + 8746919 = 8747086
239 + 8746847 = 8747086
353 + 8746733 = 8747086
389 + 8746697 = 8747086

Showing the first eight; more decompositions exist.
