Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718842, here are decompositions:

3 + 8718839 = 8718842
19 + 8718823 = 8718842
31 + 8718811 = 8718842
43 + 8718799 = 8718842
109 + 8718733 = 8718842
193 + 8718649 = 8718842
241 + 8718601 = 8718842
271 + 8718571 = 8718842

Showing the first eight; more decompositions exist.
