Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516688, here are decompositions:

71 + 516617 = 516688
89 + 516599 = 516688
101 + 516587 = 516688
149 + 516539 = 516688
167 + 516521 = 516688
239 + 516449 = 516688
251 + 516437 = 516688
257 + 516431 = 516688

Showing the first eight; more decompositions exist.
