Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516778, here are decompositions:

89 + 516689 = 516778
167 + 516611 = 516778
179 + 516599 = 516778
191 + 516587 = 516778
239 + 516539 = 516778
257 + 516521 = 516778
347 + 516431 = 516778
401 + 516377 = 516778

Showing the first eight; more decompositions exist.
