Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487146, here are decompositions:

13 + 487133 = 487146
47 + 487099 = 487146
53 + 487093 = 487146
67 + 487079 = 487146
73 + 487073 = 487146
89 + 487057 = 487146
97 + 487049 = 487146
139 + 487007 = 487146

Showing the first eight; more decompositions exist.
