Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516640, here are decompositions:

17 + 516623 = 516640
23 + 516617 = 516640
29 + 516611 = 516640
41 + 516599 = 516640
53 + 516587 = 516640
101 + 516539 = 516640
191 + 516449 = 516640
233 + 516407 = 516640

Showing the first eight; more decompositions exist.
