Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645192, here are decompositions:

13 + 8645179 = 8645192
79 + 8645113 = 8645192
139 + 8645053 = 8645192
163 + 8645029 = 8645192
181 + 8645011 = 8645192
229 + 8644963 = 8645192
331 + 8644861 = 8645192
349 + 8644843 = 8645192

Showing the first eight; more decompositions exist.
