Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645216, here are decompositions:

37 + 8645179 = 8645216
103 + 8645113 = 8645216
163 + 8645053 = 8645216
193 + 8645023 = 8645216
313 + 8644903 = 8645216
373 + 8644843 = 8645216
487 + 8644729 = 8645216
607 + 8644609 = 8645216

Showing the first eight; more decompositions exist.
