Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713940, here are decompositions:

7 + 8713933 = 8713940
13 + 8713927 = 8713940
43 + 8713897 = 8713940
61 + 8713879 = 8713940
73 + 8713867 = 8713940
127 + 8713813 = 8713940
241 + 8713699 = 8713940
337 + 8713603 = 8713940

Showing the first eight; more decompositions exist.
