Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718830, here are decompositions:

7 + 8718823 = 8718830
19 + 8718811 = 8718830
31 + 8718799 = 8718830
37 + 8718793 = 8718830
73 + 8718757 = 8718830
97 + 8718733 = 8718830
103 + 8718727 = 8718830
157 + 8718673 = 8718830

Showing the first eight; more decompositions exist.
