Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487712, here are decompositions:

3 + 487709 = 487712
31 + 487681 = 487712
61 + 487651 = 487712
109 + 487603 = 487712
151 + 487561 = 487712
223 + 487489 = 487712
241 + 487471 = 487712
283 + 487429 = 487712

Showing the first eight; more decompositions exist.
