Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665748, here are decompositions:

31 + 8665717 = 8665748
97 + 8665651 = 8665748
181 + 8665567 = 8665748
277 + 8665471 = 8665748
307 + 8665441 = 8665748
379 + 8665369 = 8665748
541 + 8665207 = 8665748
547 + 8665201 = 8665748

Showing the first eight; more decompositions exist.
