Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488690, here are decompositions:

3 + 488687 = 488690
73 + 488617 = 488690
79 + 488611 = 488690
151 + 488539 = 488690
271 + 488419 = 488690
283 + 488407 = 488690
337 + 488353 = 488690
373 + 488317 = 488690

Showing the first eight; more decompositions exist.
