Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751086, here are decompositions:

7 + 8751079 = 8751086
73 + 8751013 = 8751086
79 + 8751007 = 8751086
139 + 8750947 = 8751086
163 + 8750923 = 8751086
193 + 8750893 = 8751086
229 + 8750857 = 8751086
277 + 8750809 = 8751086

Showing the first eight; more decompositions exist.
