Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487248, here are decompositions:

29 + 487219 = 487248
37 + 487211 = 487248
61 + 487187 = 487248
71 + 487177 = 487248
137 + 487111 = 487248
149 + 487099 = 487248
191 + 487057 = 487248
197 + 487051 = 487248

Showing the first eight; more decompositions exist.
