Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516788, here are decompositions:

31 + 516757 = 516788
61 + 516727 = 516788
67 + 516721 = 516788
79 + 516709 = 516788
109 + 516679 = 516788
199 + 516589 = 516788
271 + 516517 = 516788
331 + 516457 = 516788

Showing the first eight; more decompositions exist.
