Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481580, here are decompositions:

3 + 481577 = 481580
31 + 481549 = 481580
67 + 481513 = 481580
79 + 481501 = 481580
163 + 481417 = 481580
193 + 481387 = 481580
277 + 481303 = 481580
283 + 481297 = 481580

Showing the first eight; more decompositions exist.
