Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645174, here are decompositions:

61 + 8645113 = 8645174
103 + 8645071 = 8645174
127 + 8645047 = 8645174
151 + 8645023 = 8645174
163 + 8645011 = 8645174
211 + 8644963 = 8645174
271 + 8644903 = 8645174
313 + 8644861 = 8645174

Showing the first eight; more decompositions exist.
