Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719744, here are decompositions:

41 + 8719703 = 8719744
83 + 8719661 = 8719744
167 + 8719577 = 8719744
353 + 8719391 = 8719744
443 + 8719301 = 8719744
491 + 8719253 = 8719744
521 + 8719223 = 8719744
557 + 8719187 = 8719744

Showing the first eight; more decompositions exist.
