Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737540, here are decompositions:

11 + 8737529 = 8737540
17 + 8737523 = 8737540
59 + 8737481 = 8737540
107 + 8737433 = 8737540
113 + 8737427 = 8737540
167 + 8737373 = 8737540
191 + 8737349 = 8737540
197 + 8737343 = 8737540

Showing the first eight; more decompositions exist.
