Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742984, here are decompositions:

7 + 8742977 = 8742984
11 + 8742973 = 8742984
43 + 8742941 = 8742984
53 + 8742931 = 8742984
67 + 8742917 = 8742984
97 + 8742887 = 8742984
127 + 8742857 = 8742984
137 + 8742847 = 8742984

Showing the first eight; more decompositions exist.
