Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665072, here are decompositions:

41 + 8665031 = 8665072
113 + 8664959 = 8665072
131 + 8664941 = 8665072
281 + 8664791 = 8665072
401 + 8664671 = 8665072
491 + 8664581 = 8665072
599 + 8664473 = 8665072
641 + 8664431 = 8665072

Showing the first eight; more decompositions exist.
