Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718994, here are decompositions:

41 + 8718953 = 8718994
107 + 8718887 = 8718994
113 + 8718881 = 8718994
191 + 8718803 = 8718994
197 + 8718797 = 8718994
257 + 8718737 = 8718994
491 + 8718503 = 8718994
503 + 8718491 = 8718994

Showing the first eight; more decompositions exist.
