Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617122, here are decompositions:

13 + 8617109 = 8617122
131 + 8616991 = 8617122
211 + 8616911 = 8617122
263 + 8616859 = 8617122
313 + 8616809 = 8617122
359 + 8616763 = 8617122
389 + 8616733 = 8617122
401 + 8616721 = 8617122

Showing the first eight; more decompositions exist.
