Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487138, here are decompositions:

5 + 487133 = 487138
59 + 487079 = 487138
89 + 487049 = 487138
131 + 487007 = 487138
167 + 486971 = 487138
191 + 486947 = 487138
269 + 486869 = 487138
317 + 486821 = 487138

Showing the first eight; more decompositions exist.
