Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011640, here are decompositions:

41 + 1011599 = 1011640
53 + 1011587 = 1011640
101 + 1011539 = 1011640
131 + 1011509 = 1011640
197 + 1011443 = 1011640
233 + 1011407 = 1011640
263 + 1011377 = 1011640
269 + 1011371 = 1011640

Showing the first eight; more decompositions exist.
