Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516580, here are decompositions:

17 + 516563 = 516580
41 + 516539 = 516580
59 + 516521 = 516580
131 + 516449 = 516580
149 + 516431 = 516580
173 + 516407 = 516580
257 + 516323 = 516580
347 + 516233 = 516580

Showing the first eight; more decompositions exist.
