Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487166, here are decompositions:

67 + 487099 = 487166
73 + 487093 = 487166
109 + 487057 = 487166
223 + 486943 = 487166
349 + 486817 = 487166
397 + 486769 = 487166
409 + 486757 = 487166
487 + 486679 = 487166

Showing the first eight; more decompositions exist.
