Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719740, here are decompositions:

37 + 8719703 = 8719740
41 + 8719699 = 8719740
59 + 8719681 = 8719740
79 + 8719661 = 8719740
137 + 8719603 = 8719740
149 + 8719591 = 8719740
163 + 8719577 = 8719740
167 + 8719573 = 8719740

Showing the first eight; more decompositions exist.
