Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488780, here are decompositions:

31 + 488749 = 488780
37 + 488743 = 488780
79 + 488701 = 488780
139 + 488641 = 488780
163 + 488617 = 488780
241 + 488539 = 488780
277 + 488503 = 488780
307 + 488473 = 488780

Showing the first eight; more decompositions exist.
