Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719156, here are decompositions:

23 + 8719133 = 8719156
29 + 8719127 = 8719156
107 + 8719049 = 8719156
239 + 8718917 = 8719156
269 + 8718887 = 8719156
317 + 8718839 = 8719156
353 + 8718803 = 8719156
359 + 8718797 = 8719156

Showing the first eight; more decompositions exist.
