Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487772, here are decompositions:

3 + 487769 = 487772
31 + 487741 = 487772
211 + 487561 = 487772
283 + 487489 = 487772
349 + 487423 = 487772
409 + 487363 = 487772
661 + 487111 = 487772
673 + 487099 = 487772

Showing the first eight; more decompositions exist.
