Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488630, here are decompositions:

3 + 488627 = 488630
13 + 488617 = 488630
19 + 488611 = 488630
127 + 488503 = 488630
157 + 488473 = 488630
211 + 488419 = 488630
223 + 488407 = 488630
229 + 488401 = 488630

Showing the first eight; more decompositions exist.
