Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717972, here are decompositions:

13 + 8717959 = 8717972
103 + 8717869 = 8717972
163 + 8717809 = 8717972
181 + 8717791 = 8717972
199 + 8717773 = 8717972
223 + 8717749 = 8717972
229 + 8717743 = 8717972
283 + 8717689 = 8717972

Showing the first eight; more decompositions exist.
