Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487086, here are decompositions:

7 + 487079 = 487086
13 + 487073 = 487086
29 + 487057 = 487086
37 + 487049 = 487086
73 + 487013 = 487086
79 + 487007 = 487086
109 + 486977 = 487086
137 + 486949 = 487086

Showing the first eight; more decompositions exist.
