Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613040, here are decompositions:

71 + 8612969 = 8613040
83 + 8612957 = 8613040
113 + 8612927 = 8613040
167 + 8612873 = 8613040
179 + 8612861 = 8613040
239 + 8612801 = 8613040
263 + 8612777 = 8613040
311 + 8612729 = 8613040

Showing the first eight; more decompositions exist.
