Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720026, here are decompositions:

83 + 8719943 = 8720026
179 + 8719847 = 8720026
449 + 8719577 = 8720026
647 + 8719379 = 8720026
659 + 8719367 = 8720026
677 + 8719349 = 8720026
719 + 8719307 = 8720026
773 + 8719253 = 8720026

Showing the first eight; more decompositions exist.
