Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512850, here are decompositions:

7 + 512843 = 512850
29 + 512821 = 512850
31 + 512819 = 512850
47 + 512803 = 512850
53 + 512797 = 512850
71 + 512779 = 512850
83 + 512767 = 512850
89 + 512761 = 512850

Showing the first eight; more decompositions exist.
