Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706540, here are decompositions:

13 + 8706527 = 8706540
43 + 8706497 = 8706540
61 + 8706479 = 8706540
79 + 8706461 = 8706540
83 + 8706457 = 8706540
127 + 8706413 = 8706540
137 + 8706403 = 8706540
163 + 8706377 = 8706540

Showing the first eight; more decompositions exist.
