Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713428, here are decompositions:

7 + 8713421 = 8713428
29 + 8713399 = 8713428
79 + 8713349 = 8713428
89 + 8713339 = 8713428
109 + 8713319 = 8713428
137 + 8713291 = 8713428
167 + 8713261 = 8713428
179 + 8713249 = 8713428

Showing the first eight; more decompositions exist.
