Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645000, here are decompositions:

37 + 8644963 = 8645000
43 + 8644957 = 8645000
73 + 8644927 = 8645000
97 + 8644903 = 8645000
127 + 8644873 = 8645000
139 + 8644861 = 8645000
157 + 8644843 = 8645000
229 + 8644771 = 8645000

Showing the first eight; more decompositions exist.
