Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665826, here are decompositions:

109 + 8665717 = 8665826
193 + 8665633 = 8665826
223 + 8665603 = 8665826
283 + 8665543 = 8665826
397 + 8665429 = 8665826
457 + 8665369 = 8665826
523 + 8665303 = 8665826
607 + 8665219 = 8665826

Showing the first eight; more decompositions exist.
