Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516844, here are decompositions:

5 + 516839 = 516844
23 + 516821 = 516844
131 + 516713 = 516844
191 + 516653 = 516844
227 + 516617 = 516844
233 + 516611 = 516844
257 + 516587 = 516844
281 + 516563 = 516844

Showing the first eight; more decompositions exist.
