Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487236, here are decompositions:

17 + 487219 = 487236
23 + 487213 = 487236
53 + 487183 = 487236
59 + 487177 = 487236
103 + 487133 = 487236
137 + 487099 = 487236
157 + 487079 = 487236
163 + 487073 = 487236

Showing the first eight; more decompositions exist.
