Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665562, here are decompositions:

19 + 8665543 = 8665562
193 + 8665369 = 8665562
229 + 8665333 = 8665562
439 + 8665123 = 8665562
463 + 8665099 = 8665562
523 + 8665039 = 8665562
541 + 8665021 = 8665562
571 + 8664991 = 8665562

Showing the first eight; more decompositions exist.
