Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617072, here are decompositions:

71 + 8617001 = 8617072
83 + 8616989 = 8617072
239 + 8616833 = 8617072
251 + 8616821 = 8617072
263 + 8616809 = 8617072
311 + 8616761 = 8617072
353 + 8616719 = 8617072
383 + 8616689 = 8617072

Showing the first eight; more decompositions exist.
