Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645102, here are decompositions:

31 + 8645071 = 8645102
73 + 8645029 = 8645102
79 + 8645023 = 8645102
139 + 8644963 = 8645102
199 + 8644903 = 8645102
229 + 8644873 = 8645102
241 + 8644861 = 8645102
331 + 8644771 = 8645102

Showing the first eight; more decompositions exist.
