Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646472, here are decompositions:

71 + 8646401 = 8646472
83 + 8646389 = 8646472
173 + 8646299 = 8646472
179 + 8646293 = 8646472
239 + 8646233 = 8646472
251 + 8646221 = 8646472
353 + 8646119 = 8646472
491 + 8645981 = 8646472

Showing the first eight; more decompositions exist.
