Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487232, here are decompositions:

13 + 487219 = 487232
19 + 487213 = 487232
139 + 487093 = 487232
181 + 487051 = 487232
211 + 487021 = 487232
241 + 486991 = 487232
283 + 486949 = 487232
463 + 486769 = 487232

Showing the first eight; more decompositions exist.
