Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732940, here are decompositions:

17 + 8732923 = 8732940
19 + 8732921 = 8732940
53 + 8732887 = 8732940
61 + 8732879 = 8732940
71 + 8732869 = 8732940
79 + 8732861 = 8732940
101 + 8732839 = 8732940
107 + 8732833 = 8732940

Showing the first eight; more decompositions exist.
