Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640082, here are decompositions:

23 + 8640059 = 8640082
131 + 8639951 = 8640082
173 + 8639909 = 8640082
179 + 8639903 = 8640082
233 + 8639849 = 8640082
263 + 8639819 = 8640082
419 + 8639663 = 8640082
443 + 8639639 = 8640082

Showing the first eight; more decompositions exist.
