Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488918, here are decompositions:

97 + 488821 = 488918
127 + 488791 = 488918
139 + 488779 = 488918
229 + 488689 = 488918
277 + 488641 = 488918
307 + 488611 = 488918
379 + 488539 = 488918
499 + 488419 = 488918

Showing the first eight; more decompositions exist.
