Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488660, here are decompositions:

19 + 488641 = 488660
43 + 488617 = 488660
157 + 488503 = 488660
241 + 488419 = 488660
307 + 488353 = 488660
313 + 488347 = 488660
331 + 488329 = 488660
349 + 488311 = 488660

Showing the first eight; more decompositions exist.
