Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718982, here are decompositions:

29 + 8718953 = 8718982
101 + 8718881 = 8718982
113 + 8718869 = 8718982
131 + 8718851 = 8718982
149 + 8718833 = 8718982
179 + 8718803 = 8718982
401 + 8718581 = 8718982
443 + 8718539 = 8718982

Showing the first eight; more decompositions exist.
