Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516940, here are decompositions:

29 + 516911 = 516940
101 + 516839 = 516940
227 + 516713 = 516940
239 + 516701 = 516940
251 + 516689 = 516940
317 + 516623 = 516940
353 + 516587 = 516940
401 + 516539 = 516940

Showing the first eight; more decompositions exist.
