Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665144, here are decompositions:

71 + 8665073 = 8665144
113 + 8665031 = 8665144
167 + 8664977 = 8665144
197 + 8664947 = 8665144
281 + 8664863 = 8665144
353 + 8664791 = 8665144
401 + 8664743 = 8665144
443 + 8664701 = 8665144

Showing the first eight; more decompositions exist.
