Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512888, here are decompositions:

67 + 512821 = 512888
109 + 512779 = 512888
127 + 512761 = 512888
307 + 512581 = 512888
367 + 512521 = 512888
421 + 512467 = 512888
499 + 512389 = 512888
577 + 512311 = 512888

Showing the first eight; more decompositions exist.
