Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512886, here are decompositions:

37 + 512849 = 512886
43 + 512843 = 512886
67 + 512819 = 512886
83 + 512803 = 512886
89 + 512797 = 512886
107 + 512779 = 512886
139 + 512747 = 512886
173 + 512713 = 512886

Showing the first eight; more decompositions exist.
