Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516988, here are decompositions:

11 + 516977 = 516988
29 + 516959 = 516988
41 + 516947 = 516988
149 + 516839 = 516988
167 + 516821 = 516988
389 + 516599 = 516988
401 + 516587 = 516988
449 + 516539 = 516988

Showing the first eight; more decompositions exist.
