Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487208, here are decompositions:

31 + 487177 = 487208
97 + 487111 = 487208
109 + 487099 = 487208
151 + 487057 = 487208
157 + 487051 = 487208
439 + 486769 = 487208
487 + 486721 = 487208
541 + 486667 = 487208

Showing the first eight; more decompositions exist.
