Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665790, here are decompositions:

13 + 8665777 = 8665790
73 + 8665717 = 8665790
139 + 8665651 = 8665790
157 + 8665633 = 8665790
223 + 8665567 = 8665790
229 + 8665561 = 8665790
349 + 8665441 = 8665790
421 + 8665369 = 8665790

Showing the first eight; more decompositions exist.
