Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718972, here are decompositions:

19 + 8718953 = 8718972
23 + 8718949 = 8718972
103 + 8718869 = 8718972
113 + 8718859 = 8718972
139 + 8718833 = 8718972
149 + 8718823 = 8718972
173 + 8718799 = 8718972
179 + 8718793 = 8718972

Showing the first eight; more decompositions exist.
